Complaint Review: Collect Pros

I recieved a letter by this company claiming I owe $79.95 for a product purchase of Pure Garcinia. This is the first I am learning about this so I tried calling 800 number to dispute and there is no way to reach an agent as I made several attempts. I looked up company on their "website" and tried to send and email stating this however it was sent to my inbox as a failed attempt the delivery address was not correct. I went back to website and did it again same thing happened every time I did it. Do not pay these people as its a rip off. There is no way of making contact with them either! And I have never made such a purchase, nor attempted or owe the alleged debt!!!!!
