Incorrect information given

I have a contract with Cell C, which is arrears. I called Cell C on the 4th of May regarding my account, I wanted the outstanding balance and the banking details so that I can settle the account. I was referred to the collections/legal department for my query, they gave me an account no and settlement amount of R2349.00 to pay which i did pay. Today i called Cell C again to check if my payment reflects as yet so that i can close the account, i was advised that the account was handed over to SSDA in April and i need to speak to them regarding the issues. I called them and i was told that the payment was not made to them and to cell c so i need to take it up with cell c, they even told me a different balance to what Cell C told me to pay. When i called Cell C again they still told me to call SSDA and that there is nothing that they can help me with, first of all i called Cell C to get the right information but today i'm being treated though as if i just decided to make that payment to Cell C, My money was paid to cell c but seems like they don't even want to get involved in resolving the issue, i am being taken back and forth over something that could have been avoided. Please refund my money so that i can pay it to SSDA or allocate it accordingly.
