Purchased 2 x 64GB i-Easy Drive will not work

I recently purchased 2 x 64GB i-Easy Drive through ad on Facebook. I previously had a 32GB works great, these 64GB do not work at all. Tried to contact developer/company but everything is in Chinese...I feel totally ripped off. Now will contact Facebook about this company unless someone contacts me ASAP as these were expensive!!!!
