CLOSED ACCOUNT STILL LISTED AS OPEN

I took a revolving credit plan with Standard bank in July 2018 and It was paid off in September 2018. Its six months later now but Standard bank has not instructed the credit bureau to clear the loan from my name. I went to Standard bank to inquire and I was told to call Trans-union and ask them to update my credit history. I have spoken to credit bureau and I was told that Standard bank needs to instruct them to clear my name even if I have proof of payment or proof that the account is closed. This is crippling my borrowing power!
