Still the same issue after WEEKS

Okay, so this is now my THIRD complaint regarding the SAME issue on hellopeter.com. I have now spoken to probably 20 people ALL of which would resolve the matter at hand, ALL of which would get back to me. Every single person I speak to acknowledges that ADT incorrectly put me on ITC and that it has since been removed. The bank however STILL picks it up and I have now been struggling for over a week JUST to get a letter out of you stating that the issue has been cleared up and the account has always been paid in full. Your accounts department, my so-called credit controller, and the supervisors there have not answered a single call in over 15 attempts and not once have they returned a call or email. What is the point of escalating an issue if no one takes ownership of it? I want you to provide me with proof that the issue has been cleared up and that my name has been removed so I can send it to my bank. Get your house in order!
