Digital Sourcing Aars Trick me into buying their products, i didn't click on order button

I saw the add on facebook i chected it out, they ask personal imformation like adress and name i did then i saw the price was too high and closed the wesite, days later i get a email saying "your package has been shipped when i never order it in the first place..

i'm trying to return the items but i was told that i cannot send them back because the items are flamable and contain alcohol which the post store does not allow.

i don't know what else to do because i can't pay such high price.
