When are we ending this hideous relationship!

Apparently I owe Cell C R1245.18. But I apparently also owe a R147. And then tonight R1242.18 is debited from my account. Yet my contract ended in Feb this year. What am I being billed for. I dont have anything in current on my invoices. My simcard which had airtime loaded onto it from my last payments has been inactive as I could not do a sim swop for God knows what reason. Can somebody from Cell C call me to tell me what the hell is going on. Also, I paid the R147 which showed current. Yet that was not taken off this amazing large sum that I owe. Please contact me between 1pm and 2pm. I've actually sent an email about this to a Kagiso and received no response.
