Terrible Capitec service and App

My mom lost her card, so Monday, 6 September, we drove to the Bloemfontein Capitec branch to create a new one. This went fine, but the pin was was not working. Luckily we did not leave the branch and went to tell the people there. They told us she would have to pay a fee to renew her card again and we agreed. But when we tried the pin again, it still was not working, we even showed the teller over there to see for himself and they witnessed for themselves how buggy their system was being and changed it again. It was working for a while, however, this morning (11 September) she tried accessing the account via Capitec App again and it is was suddenly blocked (The card and account has been suspended). The people on the call centers are not even trying to fix the issue, they are adamant that we must have entered the wrong pin and just hang up. My mom has been using the same pin for years now, so this is basically impossible. Worse part is she cant even buy petrol to drive to the nearest city, Bloemfontein, to go fix this issue. I truly feel this is an error on their part (their servers or system), but they refuse to accept it and insist we must have made the errors instead of trying to resolve the issue, especially when they that this error has occurred earlier this week
