i closed a cheque account i had with the bank .

I had a cheque account with standard bank which i closed in August of 2013 because i was not happy with their service to my suprise in 2014 oct. I was called by their lawyers saying i owe standard back for the same cheque account that i have closed , i went to the same branch and i was assisted by the same *********** guy by the name of raymond bhungane who gave me an attitude and said his manager will call me and that never happened and today i got a call again from the lawyers for the same query which i thought i was resolved ,so someone must fix this mess quickly before i involve my lawyers.
