3 REQUESTS / 10 MONTHS - STILL NO RESPONSE TO CHANGE DETAILS

I sent a request to RCS on 04 November 2020 to update my contact details as my address and contact number changed. They required a signed copy of my identity document to be sent to ***. I recieved no response. On 22 January 2021 I sent the document again to the email address. No response and still no change of either my address or my contact number on my statements. I subsequently found out that my card was blocked and I had to go to Makro Alberton to have it unblocked with much frustration and almost an hour of my time wasted. This morning I wanted to do an online transaction at Makro and use my card for payment. The OTP was sent to my OLD NUMBER which means that the change of contact HAS STILL NOT BEEN DONE. I phoned RCS and was just told to send my ID with signatures again. For goodness sake, WHAT DOES ONE HAVE TO DO TO GET YOUR DETAILS UPDATED WITH THESE PEOPLE.... I can do no online transactions neither can I do a balance check simply because of the inability of RCS to perform a simple request from the customer.
