Hobbies Discount Facebook Took my money and did not deliver item ordered. Internet

I clicked on "Hobbies Discount" from Facebook and on 11/18/2016 ordered night vision binoculars for $49.50 + $9.50 for Shipping. I tried to contact Hobbies Discount by email and phone on multiple occasions and could not connect with anyone. I also notified Facebook that this was a fraudulent site and asked them to remove it. It is now 1/8/2017 and Hobbies Discount is still posting on Facebbok. Facebook says they cannot help me get a refund, but have failed to remove this advertiser from their site. I now consider Facebook complacent and negligent in not removing this fraudulent web site and am considering suing both facebook and Hobbies discount (if I can find them).
