zbiddy.com Unknown charges on invoice & at bank Miami Florida

 I received an offer through "MyPoints" for a site called "UnlockYourLuck".  I bid on a Cruise for 2 to the Bahamas & won!  I was taken to a page to cashout.  My cost was .37, there was a 9.99 transaction fee.  They made another offer that I accepted for 19.99.  When I checked out, it first said that my card was denied.  When I got to the completed screen there was an additional purchase for their bidding tokens for $79.00!!!!  & the original card submitted had been charged multiple times.  Be AWARE if you get an offer for this site.  My bank put a block on my card & then did absolutely NOTHING about the charges!  Hopefully these bastages will credit me back.  Thank you for letting me vent!
