I terminated my contract with XXXX in XXXX 2013 in my belief that they violated the contract terms. I received a final invoice that included {$100.00} early termination fee. I formally disputed the {$100.00} and sent a check for {$78.00} with a letter outlining the reasons for my dispute. I specifically requested through this letter that should XXXX disagree with my reasoning to contact me by mail and we could work through the dispute. I heard nothing for over a year, and because the check for {$78.00} cleared my account, my assumption was there was no dispute by XXXX. XXXX weeks ago a XXXX salesperson came to my door trying to regain my business. He somewhat convinced me that the XXXX internal culture was changing for the positive, with an improved consumer focus. I started taking steps forward toward reattaining their service based on this representation. When I provided my SSN, the salesperson came back and told me I owed {$100.00}, and that management would not move forward. There were XXXX prongs to my reason for terminating - the local XXXX focused on XXXX, which I disagree with. The same day I was informed of this, I started to receive numerous calls from XXXX collection agency. I have received a letter from the agency as well. I attempted to work towards resolution with this company through their salesperson, but it appears that a local decision was made to hold their ground regarding the {$100.00}. As it was communicated to me the attitude of decision-makers appears to be as arbitrary and spiteful. The local XXXX group appeared to form their opinion, and took immediate negative action against me through the Collection Agency over one year without providing me the benefit of responding to my written letter of a year prior, and leaving me with the impression through their silence, and cleared personal check that no dispute existed. These tactics are clearly unprofessional in my view, and I appreciate if you could assist with having collection ceased with no affect to my credit record. Thank you.
