Sweepstakes ClearningHouse Purchased a faulty digital camcorder

I purchased an Onmi2 Digital Camcorder and it turned it on when I first bought it and it worked but, stored it away until I could purchase 2 Sdcards ...when I went installed the cards several months later the camcorder didn't work ....I tried charging it and it doesn't charge although it shows a red charching light on...the software is only for windows 7 & 8 and I only have a OS MAC so it's not even compatible with my laptop....I just want a new  camcorder ...I am unable to find their address and phone number to contact them....I don't have any money to return it and on a limited income so this was a bummer I can't even use something I really wanted....They seem to sell cheap items and charge alot...I bought a safe from them which seems very good but, I paid them in full but, they left out to mention a COD payment when UPS delievered the item...they seem shady and I will not buy another item from them again...their products are very cheap and break easily and they charge alot for them.
