Edgars terrible service

Beginning of February I lodged a complaint with Edgars to close a ********** account opened using my ****** ID. The account owes money and Edgars have reported me to credit bureaus and have affected my credit score adversely. I provided all the necessary documents in store at Bayside Mall CPT to assist the investigation. I did countless follow ups; in store, calls and emails, to find out if the account has been closed or how the investigation is going. So far I have never received any feedback from Edgars ***** Department. I was advised that investigation would take 10-15 days but it has been around 2 months now. When I called them today I was told the person dealing with my account is on lunch but it seems my case has just been sitting on a desk and not being worked. How do I get help with this? I am seriously annoyed by the service from Edgars.
