Payment not allocated

Hi

I have made a payment on the 25/11/2016 to Cell C and proof of payment on my back account and know they want a detailed bank statement from me. I think this is really bad from them it is 9 month and they can not find my payment. I have gone to Nedbank they even have send the proof of payment for me as there Call Center ask me to do The Glen Cell c Staff is also trying to help me but the account department is hopeless. And they do not want me to upgrade because of this and the mistake is not even me it is Cell C Accounts. I have send proof of payment to all kind of emails that Cell C Call Center has given me , and it is still not sorted, I think they have know knowledge off what they are doing, i also feel they can not demand from me a detailed bank statement that I have send on numerous of times. i this do not get sort shortly I will take it one step Future
