Collection agency dunning me for an old debt

About the moving clause in the contract, it was something along the lines of 50 miles from any of their facilities, and no, I did not confuse that with simply moving 50 miles from my original address. I moved to a very remote and rural part of Eastern NC that had no gyms of any description at that time, just city-owned rec centers. The manager of the gym I belonged to in Phoenix did verify that I would be living too far from any of the chain’s facilities to remain a member and assured me that all I would need to get out of the contract was some proof of my new address in rural NC, which I gave. And as I mentioned, both the contract and the associated paperwork regarding proof of new residence were tossed out by a family member in the summer of 1998 when I was away living overseas. We foolishly thought this matter was behind us at that time.
Hope this helps!
