Pathetic service from *******.

Last year my banking details changed. I phoned Tracetec and the agenda said it is quite simple as I just need to give them my new banking details over the phone as all calls are recorded and they have verified me by means of the security questions. I though that was very nice as you usually have to send documents via email. A few months back I received an sms or email from tracetec stating that I own the a sum of money for 6 months that I did not pay. I ****ing refuse to pay it. I have so many debit orders that go off I never even realized it was not going off of my account. And Tracetec is to pathetic to let me know sooner so I mailed back and told Tracetec to cancel my contract as I don't have that kind if money. That was 3 month ago and I still get emails and sms's and I keep replaying to these mails and cc in [Email Removed] but no one ever replies. Please stay away from these poeple as they ate bad communicators. They can't even let you know that they did not receive your money. I mean I understand that they can't notify or call everyone but surely if your account goes to 90 days they should notify you that the amount can be settled while it is still reasonable amount.
