Evolution Worldwide Limited Did not refund money for merchandise returned as promised and advertised Honk Kong, Internet

I ordered a tablet PC from this company in February, 2012.  It wouldn't hold a charge, so I was instructed by them to return it for a replacement or refund.  I chose replacement and when I got that one, it also would not work, so I was instructed on how to return it for a refund of the purchase price.  I was told 2 weeks ago that the money had been refunded to Pay Pal, but it has not.  I called Pay Pal today and they have no record of a refund from Evolution Worldwide Limited to my account.  I think they lied to me and the 45 day time limit from the date of the original purchase as passed and Pay Pal won't do anything.  So, I'm filing this report hoping that something can be done.

Thank you.
