Not able to trace my payment and then cancel my contract

On 3rd October I paid my CellC account R700.00. I was in arrears and my data line was disconnected. Unfortunately I used the incorrect reference number but send an e-mail to their "proof of payment" e-mail. On the 11th I was handed over to Nudebt, which phoned me daily and the more proofs I send to Nudebt and CellC customer services the less I got helped. One one of my correspondence I said I want my account sorted out or they must cancel the contract and pay me back the R700-00 I've paid. In the meanwhile I've paid this month's subscription as well. It's a nice contract and I would like to keep that. Yesterday I went onto Facebook and tell my story. This morning I was called to say I still owe R35 something and that my account was deactivated. To get a data line again I must apply for a new contract. I was Moses Mo***eng that I should speak to the manager who deactivated my account. He is the only one that can help me and they are only in after 8. Moses said he will get the manager to contact me. Well it is 15h30 now and I'm still waiting.
