Complaint Review: Castle Credit Corporation

I was stationed at Camp Lejeune in Jacksonville, NC. People that are working for this company go around offering a free pizza if you come to their office and sign up for their deal. Well, being the naive young Marine I was, I signed up and owe them well over a thousand dollars for services they never delivered.

I was told I could call and cancel the deal at any time. Well, I called to cancel and I was then told that I also signed the agreement that says they can change the terms of the contract at any time...and they happened to change the terms so that I couldn't cancel.
Can anyone tell me if I will get bad credit if I refuse to make any more payments with this company?

Castle Credit Corporation is targeting military families everywhere, this is a disgrace.
