****med between DHA And FNB

FNB issued a *****elant credit with my passport that was at time in DHA and with a credit limit of approx 144,000.00 I have received numerous calls from the debt collector and to be told I need to resolve at the FNb branch with the disgusting service that I have to phone for assistance, the to be told I have to go the police station and to be told that FNB has to.provide me with all the proof.. I just can't understand that I have to prove where in fact between FNB and DHA are the ********s and I have to be up and down to clear my name and just can't get anything from FNB o just get no assistance with the staff behind their branch either I must phone and not in the branch and then police station but have nothing from FNB to assist the police in opening a case.. surely I'm the innocent one here but I'm getting treated as the ********.. disgusting on FNB I have never had an account with them and never Wii!!
