nedbank credit card nightmare - beware !!!

Ok,August 2024,my nedbank credit card does not want to work anymore. I go into branch,order a new card. Get new card.Make payment as usual in september and october, but my mistake. I use the reference number of the old card, and not the new card. I take that on me. Nedbank does not notify me in those 2 months that payment was not received in correct account. Receive sms from HP attorneys, nedbanks collection agents. send them proof of payments, payments are found and allocated to correct account, they notify me of my mistake, I correct the reference/account number and continue making payment. Then nedbank/HP attorneys notify me, that I can no longer use my credit card, but I still need to pay off the outstanding amount..ok, not happy about it. All because I made 2 payments to wrong account number.Continue making payments, paying off my debt. Come March 2025. Log into my clearscore account, my credit score fell by 18 points. Check what the reason is. Nedbank account " In Default" payments not made for 4 months. I send the proof of payments to HP attorneys, send it to nedbank. No feedback from anyone. Phone them. Now I have to pay 70k in one payment to clear that account. They have loaded that whole amount on my ITC. Nedbank is saying I am not making payments, but I do make payments and I have sent them proof of payments. This is complete and utter BS. Where must I get 70k just to pay of these ****** ? I will never do business with them again, and I will advise anyone that I know and that asks me about nedbank. But here is the best of all. Before the card failed on me. I made payment for more than the minimum amount. nedbank..******..no humanity..no understanding..never again.
