Changing Banks

So I had a term loan with Standard Bank and due to covid 19, I had to make an insurance claim which paid for 5 installments. for 2 Installments, everything was fine until standard bank decided to send incorrect information to the credit bureaus that I missed payments which were covered by the insurance, because of this wrong update to the credit bureaus, I ended up not being able to get home loan financing with any other bank but the very standard bank with a higher interest. (prime plus 1). there eventually fixed this and I saw today that my credit profile shows that I have not missed payments. their U-count reward program continue to charge me even though they sent me a message saying I wont get any points since my accounts are in areas. I have been on the phone with them for hours without assistance since the collections department say my accounts are in order, but the ucount section maintain I am owing standard bank.
