Oh dear ,where do I start. Changed from talktalk as I was with vodaphone mobile and decided to have a one collective account. Firstly they lost my phone number from talktalk, I was told to have a word with talktalk about recovering my number, one can only imagine what talktalk said to me. I was told at ordering that I would get evening and weekend calls with my plan, this was not the case ,however they did offer me compensation. Regarding my phone I was on pay monthly and when my contract ended I was offered a sim only account if I was happy with the phone which at the time I was, however since then the battery is failing affecting the camera. I was told when offered sim only that I could upgrade my phone at any time, not the case, they claim I am tied into a sim only contract and would have to pay or wait to upgrade. I should never have moved to vodaphone and cant wait to leave them.
