The technology doesn't exist

It's been 1 month and getting a Makro RCS card is already the worst decision I've ever made. First I struggled to actually make a purchase at one of their partner stores that they advertise you can purchase at. Now all I want to do is manage my credit, If i try to login to the app, or self service, or website, or any of these features they say they have, I can't get in. It tells me the pin is wrong and to call the call center. I call the call centre number that the app tells me to (which tells me it's Queenspark by the way, not makro) and the robot will repeat the options over and over because it actually doesn't register any of the selections. The same thing happens when you phone the makro line listed on the statement. I then try to use the USSD and it tells me to open an account. I literally just want to be able to check my balance and ensure my payment was received.
