Consumer Redressal

My father Mr.Atul kumar Goel ,an ex-SBI employee ,who died on 1 march 2011 , had a SBI credit card which was used on 08-August-2011 to issue a banker\'s cheque of amount 9000/- to my brother Mr. Abhijeet Goel,however the cheque was not cashed by the branch, and we were asked to submit some documents(Death Certificate,etc) which were submitted to the branch(Gurgoan) in second attempt in the month of july this year .However we received no confirmation nor any response of any sort.And it has already been two months still we have received the payment. I am sick of contacting the branch again and again to solve the matter ,however there is no attempt to solve the problem.Is this the way SBI people treat a person.It is totally disgusting ,unprofessional and unethical to treat a customer like this.
