Complaint Review: Nuvajen Anti-Aging serum

     Ordered online which says free trial and just to pay $4.99 for shipping and handling, but Nuvajen charged me with $6.94. 

     I wanted to returned the product because it bulged my face, but when I recieved the product it has no returned address and no receipt.

     Nuvajen never sent any account statement through mail or email to me, I never recieved any attempts of collection from Nuvajen, so how would I know that I have this supposed existing amount to pay? I could have dispute this amount 8 months ago. And got the shock for the day when I recieved a notice yesterday July 3 from Dar Waterfront that this said amount was sold to them a collection agency.
