Healthy Online Services Canceled Free Trial But Now They Are Claiming I didn't And Threatening to Send to Collection Agency Scottsdale, Arizona

Update:  I called up the number listed on the letter (1-877-537-2434) for Healthy Online Services accounting department and spoke with Brandon and explained the entire situation.  I told him that I know it is a scam, I know that similar companies have already been sued by several state attorney generals and have lost, I told him that I have already reported them to the Attorney Generals office and BBB in several states (AZ, MN, NJ, FL) as well as the Internet Crime Complaint Center (FBI).  Brandon finally agreed to waive the entire $133.95 fee and confirmed that I would never hear from them or any third party collection agency.  Then 7 days later I received a letter from a Tiburon Financial L.L.C. collection agency attempting to reclaim this debt.  I was very surprised to find that Tiburon has an A+ rating with the BBB and seemed to be a relatively reputable company.  I spoke with a customer service rep from Tiburon who was actually very friendly and very helpful.  I  explained the entire situation to him and informed him of the fraudulent nature of the company they were collecting for.  He acknowledged that they had been receiving a number of complaints in regards to their collections for Healthy Online Services.  He said that he would file a dispute disposition and that it would be sent back to the company.  I would most likely not hear back from either of them.  He also confided in me that I need not worry about this affecting my credit report as the company does not have my social security number.  Just to be safe, I sent a letter (by certified mail with delivery confirmation) to the collection agency requesting a validation of the debt including the name and address of the original creditor (according to the Federal Trace Commision, in 15 U.S.C. 1692g).  Hopefully this is the last I hear from any of these clowns.  It is nice to know that they do not have the ability to affect my credit score without having my social security #.  All they have is my name, cell phone #, and my apartment address (am leaving within a year); this provides a very tenuous link to the rest of my finances.
