He is currently in Russia and his card was blocked but thankfully,, He got his card and coupon after 1 year of trying. Now I've been going to branches trying to get help because when he enters his pin it says wrong pin but I got no assistance.. I've been trying to call Capitec Bank but still nothing. Please do something because it's been more than 12months now and since we had communication from you guys we had Hope that it's going to get fixed but now we're just as confused!!!!
