Bad report on my ClearScore

I paid my account on the 27th November 2025 in store at MrPrice Home Canal Walk like I've been doing all these years. On this day after making my payment they had a technical problem and couldn't print my receipt. I only had my bank receipt because I paid with my card. The cashier said it's okay I don't need the store receipt as my bank receipt is proof that I paid my account. Low and behold, the first week of December 2025, I received a message from their accounts department stating that my account is in arrears. I went to the store to clear this matter. The store manager said its not a problem and will be sorted asap. This reflected on my ClearScore as a slow payer and it started affecting my business as I'm a property investor. Making it difficult to apply for credit. I went back and forth for months with the store manager and his assistant to have my name cleared on my ClearScore but they keep on telling me lies. It's now almost a year and I'm still waiting for them to sort out this problem they created. When I'm in the store looking for them they hide themselves from me. I want my good name restored, please. Fix what you have caused. To people out there, never leave without your proof of payment, it will bite you at the end.
