I'd give them another call and insist on speaking to the duty manager and explain that the onus is on them to prove that kind of abnormal usage. There's nothing in the Data Protection Act that would prohibit them from sending you information about your account. Don't stand for that kind of twaddle from them. I would contact your bank too and get them to return any Direct Debits the operator intends to take using the "Payer disputes charge" code they have available (means that the operator won't get even more wound up that you've cancelled the DD) but they won't be able to take money from your account.
I escalated my query to the call centre manager when I was liasing with them for the 1st time and I made no absolutely any progress whats so ever.
Without seeing some sort of breakdown of costs things can't really move forward.
Dr Who, I had my Nokia in use as a modem for a short period of time, but this was for a few hours at the most and this was just general browsing, definately nothing that would amount to 1.5GB of downloads in that short space of time, I would be chuffed at downloading that amount of data in a few hours from my fixed broadband connection! Again until I see a breakdown, I cannot move forward.
Someone that was in a similar situation and had theirs resolved suggested to me that I email a complaint to the Vodafone CEO, Customer relations dept, Customer services and cc in, citizens advice, OFCOM, watchdog, trading standards and my local press, detailing everything that had happened. They advised me to put in there an offer of them moving me onto their USB dongle 3GB data plan at £15 a month to reach an amicable agreement.
Thank you for your advice re the direct debit Phil, I will call my bank straight away.
What are peoples views on this?
