Jet\RCS messing up my credit record

Jet/RCS is messing up my credit record. Now my account shows that is in arrears, according to them I did not pay end of November when I have actually duplicated the payment. I payed on the 26/11/2024 and again on the 03/12/2024 using the ozow link that was sent to me. Upon realizing that the payment is not relfecting I then sent an email on the 12th to *** with two proofs of payments, there was no response I then resent them again on the 14th explaining my situation. I got a response saying I have used the wrong acc and the wrong reference. The payment was made via the ozow link that was sent to me, for someone who should know how ozow link work to say that to me I was so surprised. According to my understanding from using it for my other accounts, is that the link is personalized, one just click on the link and it takes them to where you need to put your bank card details you don't even put the amount as it is already there. Then I got another email on 17/12/2024 to say my account was removed from the collections department, I was so relieved. On the 23\12\2024 I went to Jet wanting to buy something and boom my account is in arrears! They made me talk to one of the very rude colored lady from the call center who made it sounds like it is my fault that the payment is not reflecting because I chose to use the ozow link! Why would RCS send us the link and now we are blamed for using it. She told me payments take 7-14 days to be allocated, and today again I get a call + an email stating the same problem I really don't know how to explain myself anymore. Can someone please help me in this regard.
