Progressive Business Publications Rip-Off Unsolicited phone call to send Free newsletters. Unwanted newsletters not received, Internet

We received a telemarketing call in September (so says Angel at International Credit Collections) of last year offering us a free newsletter.  I declined.  She convinced me that it was free, with no obligation what-so-ever.  So, I said "OK" and then forgot about it.  Is that still a SLAM?  Never received any newsletters, but yesterday I got a call from a Collections Agency in the 607 area code. 

Upion investigation, Progressive Business Publications had sent a collections invoice to "International Credit Collections" for $299.  I complained, but Angel at the Collections Agency couldn't do anything about it, wouldn't accept my explination, wouldn't identify a name of a person at the company or a phone number of this company so I could call and complain.  However, they would "settle" for $195, but I refused as I neither obligated my self or this company to get any costly newsletters. 

By going to "ripoffreport.com" I was able to at least identify the company doing these Scams.  Our Colorado State Attorney General has several similar complaints, but won't prosecute because they are out-of-state in Pennsylvania.  I've written to the Pennsylvania State Attorney General, and will await a response.  In the meantime, I will attempt to dispute this bill, the collections agency demand, and the unreceived newsletters issue.
