Vodafone are typical of a large corporate entity that cannot provide proper customer service and you can never get anything done properly by. For a brief while I was using a large amount of mobile data, and I received texts telling me I was approaching my daily allowance. I upgraded my date allowance to cover this, but still kept getting the texts. I called them and the operative confirmed I was nowhere near my daily (or monthly) allowance. I asked why I was still receiving the texts and she didn't know. I asked her to stop them and she said there was no way of doing so! For the rest of my contract I periodically received these erroneous texts. I also tried in vain to opt out of their continuous marketing texts for events/services I wasn't interested in. The message said text stop to this number, but you can never send a text to that number, it always fails. When my contract was coming to an end I found a sim only deal for a quarter of what I was paying Vodafone and requested a code to transfer my number to the new provider. This went ok and I cancelled my direct debit after the last month was paid. I never received any bill from Vodafone, but I did get a text saying I had not paid my last bill, which i ignored because i had. Six months later I get demand letters from CCS Collections for an £19.44 unpaid bill, that I have never received and don't know what it is for, and is as far as I can see for nothing as I paid my contract up to the end. Poor customer service, bombard you with marketing you can't stop, send irrelevant messages about data limits you are nowhere near, and then bill you for not providing any service after you have swithed provider. I will never use Vodafone again.
