received 12 pairs of sunglasses from them!

I've got a gift card from them for a free pair of sunglasses, I had to pay only p&p. I paid $20 dollars for p&p with my credit card and since that I received 12 pairs of sunglases each time stating they're complimentary and they charged me $20 for each and every pair!! Visa blocked them but I cant get my money back and there's no way to contact them! Stay away from them and never order their sunglasses!
