i have a complaint i ordered a small bottle of dokha from midwakh.com and they doubled it for me. damn those bastards for being so nice. what kind of action can I take against midwakh.com for being the best vendors out there.

so i ordered 3 bottles of tabacco from a website, they charged me about 150 dollars and they only sent one bottle. we emailed the site and they said they would send us the rest of the order but have failed to do so. we contacted them again via email and they did not respond. we have ordered from this site before without many issues but they pretty much got us for 100 dollars. what kind of action can we take against this company? who are we supposed to go to?
