Quick to list - Slow to assist!

I have had my Game(RCS) card for over 8years and been paying my account via EFT every month. I usually pay on the 1st day of the month as they pick up my payments, however last year 2021 i made an early payment due to all the public holidays. I made payment towards my account on 1st December 2021 for end Nov, and i made another payment on 30 December for December payment. So now surprisingly they did and can not pick up my payment made on the 30th December 2021. I have been receiving calls, emails and sms's everyday since 07/01/2022 from RCS creditors requesting payment. No matter what i respond and tell them, i receive another call the following day. I have sent them proof of payment as well a copy of my bank statement to proof that payment went through...Still, i receive calls & sms's. Besides the fact that this is frustrating, i now am blocked using my card and credit i currently have available.

Prior to this, in December 2021, i went to Checkers to purchase goods and put this on my RCS card and as per their procedures Checkers needs to call them and confirm my details and for over 45min the branch manger was on a call trying to hold for them and guess what? NO ANSWER! Thus i could not use my card and felt absolutely ridiculous having to put my purchases back. I sent an mail to RCS on 23 December 2021 (***) regarding my complaint in this regards and still today have not have had a response nor an apology.

So they are quick to list someone for NO reason, but slow to see their faults.
