RSC should close down their call centre and their business

Picknpay changed my cell no without even notifying me and when I did a balance enquiry the card blocked because I did a balance enquiry from my cell no, I went to the store at 23 May at 13.00 and wanted to buy two gas heaters, my card declined and I called rcs customers service at 13.12, I then had to send a copy of my id tot he RCS ***** dpt which took 20 minutes, I held on the phone from 12.12 to 13.37 trying to get my card unblocked and the agent dropped the call on me, the consultants didnt even bother calling me back, I called back a second time, had to explain my whole story again, then the agent dropped the call again, called a 3rd time, was transferred to the ***** dpt, held on for 5 minutes, no answer, then called again, held on for another 10 minutes, just to be told they cant unblock my card as they have my old id, I got so mad I told the store to refund me my money, I will rather go to game and give them my business, we wasted almost a whole hour trying to get an unblocked card sorted out, the store staff at randridgemall was not even helpful, u lost 2000 rand because of your pathetic customer service and the pathetic service at rcs, never experienced such horrible customer service before, and all because you decided to change my number which I didnt even request, I don't know whos service is worse RCS or Picknpay, I then emailed a copy of my id from my own email to the all@***** email, and knowone has even bothered to call me back, this is really terrible service, you should close your doors
