Complaint Review: Central Credit Services

This company sent me a letter about a debt that I supposedly owed to a company in Colorado. I did use the company when I lived there, but that was around a year ago and I had given the company my updated number in the event of anything negative happening (I've had bad luck with Comcast in the past when it comes to cancelling). Anyways, they had sent me a bill for around $150.00 saying I owed them now.

At first I freaked out a little bit and thought that maybe I had forgotten something but after a phone call I realized I hadn't. I talked with billing and had to explain to them the reason for my call because my account has been long closed and is in good standing. They have ordered to send out a copy of my prior statements for in case this escalates. 

Somehow, this company hasn't tried calling me yet as far as I know, but I really don't appreciate the blatant attempt at trying to get some quick cash off me. I'm surprised they have my updated address even. No clue how they got that.
