Absa is a ****

Paid up my loan account in March 2020, however no update was done and this account still shows on my credit profile. THREE MONTHS LATER!! I spoke to their complaints department who referred me to the collections department, spoke to Shaik who confirmed that my account is paid up and is in actual fact in advance, requested my banking details for a refund since I had overpaid the account but because this took three months, there was interest which incurred which means the refund due to me has decreased which is nonsensical because they have all my details and should have called me to obtain my details for a refund as soon as it became due to me. Was told a paid up letter and a refund would processed on the 07th of July 2020, to date none of this has happened.
