US National Supplements LLC L'Envi Beauty cream Was offered a choice of 5 products as a thank you for being a customer at Chase Bank Martinez GA

I was offered a choice of 5 free gifts for being a Chase Bank customer.  I ordered L'envi with the undestanding that if I  paid shipping and handling I would recieve their cream as a gift.  About 3 weeks later, my bank account was charged $94.99.  I phoned the number listed on the charge and was told they would cancel my subscription and the good news--- they would not charge me again next month.  I explained to them I did not understand why I had been charged in the first place...they said i had had 14 days to cancel my subscription.  

The only reason I even ordered was I believed this was an offer from my bank.  When I phoned a representative he agreed to give me 15% off which he eventually turned to 50% off.  I told him no, I wanted the full amount refunded.  He  finally agreed if I returned the product they would give me a full refund.  He then gave me a code to write on my return package.  Phew, ok getting my money back.  I go to the post office and was informed that the address he gave me did not exist.

Chase bank sent me an email 3 days ago telling me they have put a temporary halt on my account because someone has been trying unsuccessfully (thank god) to access my account...just saying??

I called back today and apparently (maybe) I did not hear the address correctly...giving them a benefiit of a doubt I am going to mail back the product with some kind of verification of the enclosed return in the box...ie..have the postal employee verify the lotion is enclosed.  

I will be shocked if they credit my account but will see:(
