It is discusting that you can spend over R60000 on their cards an you only earn R200 back in green backs value!comparing to the other banks!when you want to cancel the green backs option all arrears need to be paid up even how small it might be!i do not have these stupid problems with my own bank!i am very glad i didn't follow advice and move my account to NEDBANK!very poor services!i cant even suspend the card or anything!
