My contract with O2 was coming to an end after 2 years so I was looking for a new deal. I phoned Mobiles and was told that I could take out a new deal with Vodaphone with cashback but that was all that was available, nothing with O2. They said if I wanted to cancel my O2 contract I would have to contact O2 direct. I then found a new Huawei phone on your web site with O2 and cashback. When I spoke to O2 they were very helpful and said that Mobiles could have moved the number and changed everything to the new contract for me. I wondered why the deal including the new phone is cheaper than upgrading the exiting contract.
