Complaint Review: Advanced Acai Weight Loss System

So I ordered these products from a website because it said you can try them for free and only pay shipping. They charged me $3.95 and when I received my products they weren't the ones they were advertising on the website so I called the number and the Representative told me that I am not in the system. So 1 year later exactly today I get a phone call saying they are debt collecters. The lady is saying I owe them $80.00 are you kidding me? I called the number to return the products but they kept saying I was not in the system and hung up on me. I know a few people who have been harrassed by their company's debt collecter has anyone ever done something? Because I am not paying for that and if they hurt my credit I will file a claim and speak to my lawyer. Anyone in?

PS. PLEASE DO  NOT FALL FOR THOSE SCAMS. NEVER GOING TO ORDER ONLINE AGAIN.

Regards,

Lily
