RCS card closure

I have an account with RCS, which I want to cancel, but that's not the reason for the review.

I paid in full, R4515.47, at a GAME store. I immediately contacted the call centre to help with the cancellation. The operator I spoke with told me the payment hadn't reflected on her side. She suggested I forward the proof of payment to ***, which I summarily did.

The following day I decided to try other means. I spoke with another agent via RCS chatbot, he/she told me the same thing. He/she then provided a different email to forward the proof to; ***. I did that. I haven't received any correspondence from them since.

I'm not yet angry or upset, I just want this to be resolved speedily.
