Where did my Payment go I need answers

To whom it may concern I’m worried my credit report showing that I missed a payment and there is no such thing I make sure that I pay my account every month.I made a payment on the 6th of August 2025 and I got a message from Telkom telling me I’m behind with payments. I went to the branch at Jabulani mall to get answers instant they gave me stress when I was told that bank statement is not working as a prove that you paid they need proof of payment like I must go to history payment n print it. It didn’t make any sense to me cause statement shows every transaction. But at the end I did what they were asking me to do. My concern here is why your system is not updating well now my credit report showing me that I missed a payment n that’s not true why guys are you doing that and to that payment I made I don’t understand why you don’t see on your side because payment was done with a correct reference but you guys have a guts of telling me that I’m on arrears. I really don’t like what you doing can someone please tell me the cause of this now it’s October but the payment that was made August still not appearing but you putting the blame on me by making my name bad on my credit report why
