IRRATE

i had an account with JET store and closed my account last year. to close my account account was mission as i was send from one department to the next and was told i need to cancel the policies that were activated of which i did and the account was successfully closed and i received a paid up letter. to my surprise my account shows that i am in arrears with +-R1000.00 called and spoke to the lay called Sthembile shezi told me i have a Hollard insurance asked her to escalate my request for closure till to this day account is not closed yet again. i submitted email and no response. I am not sure who handles Jet account since the take over either TFG OR RCS. Can someone fix this mess as i am unable to buy a house dues to this
