No solution

I have not paid my account... Then paid it to date, then been told that i lost my number. Call into customer services went throw the hole process of wanting to know why i lost the number. The reason i got was that i haven't paid which i can understand. In this months with me not paying the number was working perfectly fine until disconnection. Its been 20 or more days without a solution. All they say is they speaking to back office.. With no joy same feedback all the time its almost the next debit order date.
