My contract Was cancelled but I was billed

I had a contract with Telkom Mobile but the account was terminated and I was given a settlement amount, I asked the consultant if I could activate it again after paying and I was told it was canceled you need to apply for a new contract.<br> <br> Why was I billed for a contract that hasn't existed for almost a year, even after making the payment the number still doesn't work and I don't receive any data yet you continue to bill me, why do you say I still owe you and what exactly am I paying for since I no-longer have a contract with Telkom Mobile?<br> <br> If the number had been activated it would have been something else since I would also be gaining something from the whole situation, can you please rectify this and update my account on Credit bureau so that it is clear that there is no-longer a relationship between us and I have settled your account.
