Can I get my bad credit cleared up?

A few years ago roughly in the year 2002 or 2003 when I was 15-16 years old, I'm 23 now. I released some information so that my relative could open a Telus account using my name. I forgot all about the incident until 3 years ago, when I tried to apply for a loan at Royal Bank of Canada in Westlock, Alberta. My loan officer had made a few phone calls, one to the Credit Bureau which is how we found out that I had an overdue balance of 300-400 dollars on this Telus account that I had never opened. So we phoned Telus for some additional information regarding the account. Well my first and middle name came up on the account, but i have a different last name compared to the one on the account. The last name on the account was my mother's maiden last name and I had my step father's last name. What my question is, is that can I without having to pay for this outstanding balance, get my credit cleared up even though I gave my personal information out ?
