Payment not reflecting 4th complaint

This is my 4th complaint regarding my payment issue. I have made payment in store on 27 June 2022 of R 135. This is not reflecting on my account and currently my credit score is negatively affected. I have sent proof of payment to 3 different people from Mr Price who claimed they will assist me but still the problem is not resolved. I dont have the slip but the proof of payment from my account clearly shows it was a payment in store. It is totally unacceptable that I would have to struggle this much to get my payment reflecting on my account. I will go to the ombudsman if this is not sorted out as I have been patient enough to this point.
