Total disgust

I stop to put petrol, tried paying, my card declines. Go try withdraw it declines, try do an EFT,,,,,,,, IT DECLINES Now I look Luke an absolute idiot, called the call center and was on hold for 15 minutes. Get told there is a problem Sat at the petrol station for 45 mins. Missed an important appointment which I waited 3 months to get. No communication from Discovery, no apology!!! I just moved over from Nedbank, well looks like I will be going back TERRIBLE EXPERIENCE
