RCS - DON'T DO IT

I so wish I could rate less than 1 star. I have an RCS credit card - probably the most expensive way to obtain credit. This morning I tried to register on the RCS app - It didn't want to recognise my ID number, so no luck there. I then tried to register with the online self-service site - It didn't want to accept my card number, so no luck there. As a last resort, I sent a USSD code from my cell phone to view my balance - Came back with a message stating that the transaction could not be done and that the card was now blocked. The message also gave a call centre number to phone, to unblock the card. Guess what! The only damn lazy ass company in South Africa that decides it still doesn't want a call centre open during lockdown. HOW IN THE HELL can one do business like this? I suspect that someone will reply with some BS explanation as to why EVERYTHING didn't work and that there is a legitimate reason that my card was blocked. My account gets paid by debit order and this payment hasn't missed once, so not sure what BS lame excuse they will come up with. Bottom line - RCS is as **** as they were 20 years ago. I am so disgusted!!!
