Could you please assist me? I've been trying to make a payment since this morning. The app is showing my old card number, but I updated it. It asked for a R1 payment, which I made, but nothing has changed. I requested a call, but I haven’t received one yet. Can you please help or cancel my contract? I can't keep dealing with the same issue every month. You’re supposed to be debiting my account, but this is becoming really difficult for me."
