Acc suspend Without any Prior valid reason

Standard Bank is by far the worst bank ever. My Prestige cheque acc has been blocked since 26 May without any notification or warning communication because of a mere and lousy R900 payment received. Your ***** Department is horrible, Ishmael is super *********** and dishonest by informing me that My account is active when I still can't make any payments or instant Money from my Mobile App. 4 Days Later after Multiple Attempts trying to Transact, this Blue bank has failed me dismally. Its Month end, I have debits orders and purchases to make. Kgothatso Khumalo from Prestige attempted to help and still I cannot make any further transactions. I am seriously happy to close my account with you guys now!!! Disgruntled and Dissatisfied at your bleak and dim banking ethics
