Incompetency

I would like to express my frustration with RCS and their attorney's Anthony Richards and their inexperienced, *********** and very rude agents namely Miss Kadar. Short story of it all my PnP acc was in arrears, I made payment arrangements and paid it into the Std Bank PnP account before the payment date and I paid in more than the arrears amount. Yes I was advised that payment would take 3-5 days to reflect, however when I was called to make the arrangement nobody advised into which account the money should be paid in. On Monday 23/08/2021 I called the attorneys to inquire if payment was received or if it was reflecting, only then was I advised that I had made payment into the incorrect account. I was then advised that I should send proof of payment to ***, which I did and politely asked if the mail could be acknowledged. It is now the 27/08/2021 payment does still not reflect, I had received a second call this week inquiring or rather advising me that my PnP account is still in arrears after serval calls expressing my frustration and disappointment. To date I have not been advised if my payment or proof of payment has been received. This is concerning as this now affects my credit score Ref for call from Anthony Richards is ***6
