Poor Service from TFG Customer Service Call Centre

For months I have been contacting TFG about my Markham account that is showing that im in arrears on my ITC check. Whenever I apply for work or want to get finance I'm reminded of this account. I contact TFG and ask how much do I owe so that I can pay it up, close the account and submit a letter to ITC to better my record. After many many calls I am always told about the emails that they sending the legal department and supervisors to forward me a letter of clearance. This is unacceptable. All I want is to clear my name so I can move on with my life but TFG doesn't want to assist me.I have never come across a service orientated business like this before...no integrity!
