Muama Enence Logismart scam on ordering, scam on return Vilnius Lithuania

Ordered one "Muama Enence" language translator.  At check out the order form teased with "buy another for [some big discount]." I foolishly ordered a second one. Then apparently it either added four, not one, and I did not notice at checkout, or the check amount amount ramped up after the fact.  

Then I found out it was not as advertised, and wanted to return. Except they claim a "15% re-stocking fee" plus have to ship to Vilnius Lithuania.  That will be a cool $100 total, with no guanate of a credit for the rest
