Worst service from Standard Bank

Worst Service. I have been trying to verify my credit card for my cash wallet on my phone. This is now the 5th day that I have been phoning, asking them to phone me back, of course they did not, phoned again, nobody takes my call kept waiting, wasting my airtime, then wrote complaint on my Standard Bank app, got an email saying that will attend to me shortly. That was 3 days ago!! How do they keep their clients?? Please sort this out as I need to use my cash wallet!!!!!
