DONT GO TO DISCOVERY BANK !!

Discovery have changed the rules on their credit card due to their change with FNB. i have now spent hours on the phone and have unanswered emails where all i want to do is have the debit order to pay my card sorted out. i cant pay them, get them to answer me, and they are wasting my time i cant even get them to cancel my cards i want nothing more to do with them as a bank that for sure if this is how slack they are
