RCS will make me stop supporting Game and Makro

I think RCS will be the death of me. Since getting my RCS Game Store Card i have had nothing but trouble. It took 2 weekends just to get my account sorted out. I then went to make a purchase on collection of my card and can you believe they declined my first sale which was less then my qualifying criteria. In the past 6 months i have been declined 4 times even though i have sufficient credit to purchase. When asked on every occassion when i got declined, i received different responses from different people. However this weekend again, i went through to make a purchase only to get declined again. The cashier printed me out a receipt which doesnt reflect my payment of R800 for the 2nd July 2020. They contacted RCS for me to speak to a consultant but all i asked was why could i not make a purchase and even before finishing my sentence an arrogant lady has the nerve to tell me that i cant purchase if i dont pay as my account is in arrears for about R300. When i told her that i paid, she says there is no proof and it takes 5 days to update even though it has been 10 days since my payment. When i asked her to count the days since my payment, she tells me straight that i need to email her proof of payment on a Saturday in a mall. So i informed her that she is a rude and arrogant person and swore at her because she was so unhelpful. I even got feedback from many customers and staff at Game that i keep having issues with my card because i dont buy every month and that is why they block it. So by looks of things RCS expects people to just continue purchasing to avoid you card getting blocked. I had an RCS over 15 years ago and received the **** treatment and arrogance by staff and then closed my account, i thoight that they learned how to deal with people by now and that is the only reason i re-opened my account. Guess a Zebra never changes its stripes. If RCS thinks that they can treat people like they want to and just expect people to keep purchasing to avoid having issues with your card, then they are seriously mistaken. Now i will voice my opinion all over Social Media about my experience. I will pay this account up and close it immediately. Never should have even opened this account. Well like they say word of mouth is the best advertising .
