Edcon Accounts incompetence

After three attempts to rectify my account problem, I am trying this. I worked at Edcon. Now I want to continue with a normal account, which seems impossible. I have 3 accounts, the account before I worked at Edcon(Supposedly closed), the staff account(Also supposedly closed) and a new account( no credit limit, but an outstanding balance). The New account has a balance of more than the credit limit I ever had at Edcon. No one can explain it, or give me a statement or proof of where the purchases happened. About R4000 was spent since I left edcon, during which time, I never had a card or purchased anything, which leads me to believe it is *****. I went to clear water mall twice, and to highveld mall, but no one can help me. I haven't received a statement or a call from them. although they allegedly phoned me once, probably on the wrong number, and felt that that was sufficient. The Clear water mall staff member tried, but they were offline, so she couldn't assist me. The highveld mall employee, Sylvia, I think, as she wasn't wearing her name tag, was rude and unhelpful. CAN WE PLEASE RESOLVE THIS!!!
