NEDBANK IS CAUSING ISSUES FOR MY CREDIT RATING

Some 4 months back I approached Nedbank alleging credit card ***** (as they were not able to detect the ***** behave on my card). Till today I have received no response with regard to my card accept for numerous sms's saying \your card is in arrears please make payment in the sum of R5000". I was specifically asked my the person at nedbank who helped me to not make any payments on my card until the issue is resolved. I have attempted to call Nedbank and go to several branches and have published on Hello Peter before but I still have had no luck!!!!"""
