Negligence

*** On the 23/12/2015 i recieved an sms from standard bank saying African bank has requested my electronic bank statement if i did not approve this i should contact the bank. Upon calling the bank i found out that african bank issued a R10000 credit card to a person who was using my details, i went to the bank and they stopped the credit card, however the person had used R5000. The consultant who did the application also recognised that i was not the person who did the application, so they requested my finger prints and stated i have nothing to worry about as the matter is being investigated now i recieve an sms saying \my"credit card will have a some sort of policy and it will not effect \""my instalment. Why is the bank sending me these messages because they know i did not open the account? I am really disatisfied and very angry because the next thing the bank will debit my account because of they negligence. """
