customer assistance no existent

I have had a query on my account for months now. I went to a store and personally requested a complete statement off my account from date of inception. I requested same via email then only receiving a monthly statement I don't even receive via post any more as my address hadn't changed since entering into a credit facility with Ackermans. There after I have sent numerous request for this statement from date off inception listing all debits and all credits and all interest added since the day the account was opened to date. According to the National Credit Regulator I, as an consumer/client may requests a statement if I notice irregularities on my credit facility account! This is one account that will most definately be closed once outstanding balance is settled!
