Curb Weight over and over for 4months sent me unordered bottles of Lipotrim weight loss capsules Eagle, Idaho

I ordered one bottle of Lipotrim weight loss capsules at a low price. 
For 4 months, the place sent me unordered bottles, at $70 each. I tried sending the packages back, writing them, calling them--nothing worked.
I discussed the situation with my letter carrier (thank you US Post Office!) and she told me to cancel my debit card, which they had been using to charge me. I also filed a report with my credit union, reporting the fraud and asking to get my money back.
I lost probably $500, but will only get probably $300 back.
This is such a fly-by-night organization that I had trouble getting an address--they were very reluctant--and then only got a post office box.
