Cleveland Institute Of Electronics review: Billing

I signed up ($10.00 deposit) with CIE to pursue a degree program via distance learning but changed my after doing more research on the program and institution. They claimed they mailed me study materials for which I must now pay in excess of $3, 500.0 even though I never studied, acknowledged materials or ever pursue any program with the institution. They subsequently sent me a bill demanding payment in full which I immediately appealed. They promised to look into but subsequently emailed me saying if I paid $400.00 plus they would right off the debt. I replied asking what debt have I incurred if I never pursued anything in addition I removed from the last address and I was not in the country at the times they claimed they sent materials. They again promised to review but never did because I was bombarded with calls from a collection agency for payment of $3, 500.00. I again contacted CIE via phone and email and they again promised to review my matter and promised it would be recalled from collections agency. That was latter part of 2012. This account is now on my credit report and I need it off.
