Disappointing Service

I paid my account in store at Mall@Carnival on the 9th September 2020. When I called RCS to close my account I spoke to a manager named Craig that indicated there was a system glitch where payments reflected as purchases. They indicated it would take 2 weeks to resolve. On the 26th Sep I went into store here at Edgar's Mall@Carnival aside from the really **** service they cannot assist because now I more than even paid. They indicate they cannot assist without me paying. The person that took the payment on the 9th was Vusi. I found vusi and provided the proof. The proof of payment was sent via email to Craig, Vusi, 1st level complaints, Chelsea and the Almigty alone know how many other people. Every time I send an email I receive an auto reply that they will contact me in 48 hours, then an email for my account number or ID. I respond with account number and then nothing. Until I send an email again and then process starts. My wife had a similar issue which took 54 emails and a complaint on hello peter before it was resolved. Seems to me RCS or Edgar's can only make the books balance if they rob loyal customers because even if a system glitch changes a payment to a purchase as Craig indicated. This would have long been resolved unless they intent on *****ing the books. Shame on you RCS and Edgar's. I've been Edgar's client for 26years and an RCS client for about 15+ years. I always valued the service from RCS but since they took over Edgar's books and cannot resolve a simple query I'd rate RCS with negative stars.
