Blaux False advertising of return policy Internet

Website claims "hassle free returns" and 100% satisfaction guaranteed.  I purchased 2 items and after trying one out I tried to return one of them because they were not what I expected and did not perform as advertised, the Blaux portable ACs.  Support told me they only accept returns for damaged items.  I sent screen shots of their return claims from their website and support told me those images were not from their website.  I then sent support a link to their website where those claims are posted.  I simply want to return an unused item.
