One of our mobile phone contracts was ending so decided to switch providers, first provider provided Pac code and all went well, new provider sent text saying phone number would be switched next day,since then nothing, original provider says definitely left them on 12 July, new provider finally admitted today number was rejected from their system 12 July, this after me being told by customer service each day that it would be working in 24 hours, the problem now is that the number is used as part of 2 part payment verification for bank payments, also for log in on credit card site etc. Worst thing is no one can tell me where the number is. Customer services at new provider keep saying we are working on it , give it time. OK says I, I will cancel and go back to original provider, 'can't do that until the problem is sorted' So currently have no useable phone and no indication of when it will be working, any suggestions please? New provider is doing every little to help.
