EDCON employee ***** still on my ITC 3 years later

Three years ago my ID was ****** in a break in together with numerous other valuables. The ******* went to EDGARS and opened an account with the help of an EDGARS employee. They racked up a large balance on the account and years later EDGARS calls me demanding payment. I went to the store and provided details and it came to light that FICA processes were circumvented when the account was opened, and EDGARS then closed the account and "cleared the amount owing" however they did not inform ITC and now this balance is still showing on my credit record 3 years later! I try to call the accounts department, they say my details don't match their records and can't assist me.
