****ed off customer

Hi I was yesterday (Saturday) at Cape Gate mall and while i was at the till in checkers my card was declined, keep in that it only expires in 2 or 3 years and i did have money in the account, however i will not make any purchases if i did not have any money in the acc. The message the cashier gave me from the card machine is that i have reached my daily limit which was highly impossible because i had swiped at clicks for just above 200 and in the week swiped for above 2000 at checkers...then my mother had to lend a helping hand because if it was not for her i would have been even more embarrassed. So then i decided to go to an Atm which was offline, i decided to go to the Atm at the bank and believe it or not they were all offline.... So i could not withdraw any cash because all standard bank atm were offline in the mall now just imagine if i had to travel home and needed cash but i could not withdraw anywhere because seen that my card had declined at the shop i didnt wanna take a chance at a different atm.i am highly disappointed in this bank because now i contemplating on switching banks because this is pure BS!
