buybootnow.net the web site claimed and quarenteed that their boots were 100% uggs. They charged my paypal account and now when I go to their websit it says service not available so I cant get a return address, Internet

I purchased two pair of Ugg boots from an Internet company for a Christmas gift.  The site said that they have a %100 guarantee that the boots are real and authentic.  As soon as I placed my order my pay pal account was charged.  I received the boots and found out they are not real Uggs, not even close to being real Uggs.  I sent an email back to the company stating I would like to return them, and was informed that if I kept them they would take 30usd off the price if I kept them becuase returning them would cost me 45usd.  I sent an email back (Jan 5) that I did not want the boots and wanted to know what I needed to do so I could return them, and have not heard back since.  I tried to contact them agian via their website and when I type in the web address it stats that the site is not available.  I think I have been taken!
