Standard Bank definetly not moving forward

My husband has been struggling since end of April this year to sort out a credit card payment he made at an ATM in Parow Centre. After depositing the money into the ATM on the 27th April 2015 it pushed out his credit card with a slip saying technical problems. The money was not pushed out and I immediately called the number on the ATM and a lady assured me she will cancel the money coming out of the machine and the bank would remove it we just have to go into the bank to report what had happened which my husband did. He was told they would contact him as an investigation needed to be done. A few weeks later and no answer from Standard Bank but only a letter stating he is now in arrears with his credit card. He then went in again in May only to receive another we will let you know comment form the enquiry lady. A few days after that he received a sms saying the query has been sorted and he will be contacted by the bank which never happened. In June he had to go in again as the query has never been sorted as per his statements. It's been 2 weeks now and still no answer but a letter threatening to report his bad credit but he never stopped paying. SO VERY DISSAPOINTED IN STANDARD BANK
