As the formatting isn’t the best in the comments (and to make sure that everyone hears what you’re saying), I’ve just done a fresh post with some extra feedback.

Anyone else reading, head on over there.

WOW, what an experience you had there! Firstly I’m glad it’s all sorted out and that you haven’t had to pay that humongous bill.

Secondly I would like to show that Vodafone are listening and address the points you’ve made:

1) I will defiantly be feeding this back to our online team. I agree with you it’s imperative that our website makes things clear and easy to understand. We are currently in the process of upgrading our online help centre so this is the perfect time for me to give this kind of feedback.
2) We regularly review our price plans and our call charges. These have recently undergone a big improvement which I see you’re already taking advantage of, £15 for 3GB. I assume here you are talking about our roaming charges for data? We do offer these as low as we can, what we all have to bare in mind here is that Vodafone pay the network you connect to abroad for any usage whilst you are there, we then pass this charge on to our customer. Let’s also remember that we are a business and will add a profit onto these charges. That said I will again feedback you comments and who knows it may just make the difference.
3) We fully understand that a lot of our Mobile Broadband users are MAC users. We do everything we can to support you and if you pop onto our own eForum (http://forum.vodafone.co.uk) you will find additional support, (one of our eForum hosts is a MAC expert!) And yet again I will be feeding this back into the right area of the business.
4) I like this idea, a change like this is well out of my scope but I will do some digging to see how feasible this would be and find the right person/people to pass this idea onto.
5) Our email customer services team use great signatures, that explain who they are and where they are from (department wise) and they also provide great links to various things, like surveys on our service, latest products, our eForum etc. I think the problem you had was that you had been speaking to a telephone based customer service agent and they aren’t trained or developed in sending emails. They were in effect doing something outside their job role, they probably chose to be a telephone agent for the very reason that they struggle with spelling, typing etc. Regardless of this fact if an agent is offering to provide details of a call by email or letter it should be of a professional yet friendly style. If you would like us to address this with the individual agents then please contact us and we can do so. (To contact us please fill in the required section on our contact us form and in put the code FIT135 in the body of the email, this way it will come through to the eForum Team.)
6) Our call centre agents are allowed to be themselves and it is fact encouraged. We want the contact you have with Vodafone to be a relaxed and friendly one. Again this is another issue I will report back on. I would like to say a big “SORRY” to you at this point for the screw up. I know it may not mean as much as it was prompted but I promise you I mean it. 
7) I agree with you here, I like to have confirmation by email. What I would say is that if you do prefer to have contacts in writing then you are probably best suited to our email contact centre. (Use link above for this.)
We already have a system in place that prevents high bills from occurring. Clearly in your case this didn’t work. We have a department call “Credit Alerts”, their job it to monitor account usage compared to past usage and alert customers, by call, text or voicemail when the usage is unusual. If we don’t get confirmation from the customer a restriction is placed to prevent further charges being run up. At times a part payment towards the bill can be requested to reduce the charges back to a more reasonable rate. This service is supplementary and is not guaranteed to prevent high usage. Networks have a delay of up to 72 hours in the UK and as much as 3 months when outside of the UK, this means that we may not receive the call data in time to warn you.
9) This is already in place, our staff are undergoing further training on all of our data products and we will continually review and develop knowledge in this area. We also have what we call “product wizards” who know everything there is to know about a particular product/service and are on hand at all time to supports our agents.
10) Nice suggestion and again something that is already in place, my team search through Google alerts, online forums and our own eForum to provide help and support through social media channels. I hope you agree with me when I say we’re doing a fantastic job.

I hope this addresses all of your points and offers you reassurance that we do take customer in put seriously and want to do what we can to improve the service we provide. Most importantly I hope it shows we do LISTEN.

All the best,

I tried Vodafone mobile broadband, didn’t like the graphics “optimisation” and gave the thing back before the 14 day deadline (although they wouldn’t take it at first because I didn’t give them the “free” sim back).

I sometimes take mine and though I figured I shouldn’t be downloading music I had no idea that it was actually a tenner per mb!

@ Ged – that makes perfect sense to me – as it should be. The rest should and will follow I think.

@ Drew B – It is indeed shocking. If they had charged me there would have been a whole lot of bother. Let’s see what Vodafone says (if anything). I’m really hoping that they come up trumps and that my feedback is in some way useful.

And I like your 10 tips. I wonder if they’ll like them.

I use 3 for my broadband provider. If you are in a country where there is a 3 network you can avail of the 3 like home service. I used my dongle in Hong Kong earlier on in the year and still only got charged the 10 GBP I normally pay in the UK.
