Couple things here:
first - don't be an a-hole when you're trying to get someone to help you! In this case you want the vendor to refund your purchase, you need to come at them politely. Would you want to help someone who came at you in a rude manner? Amazes me how many people call customer service and talk to these people like dirt.
second - taste alone can't be the judge of authenticity. This is a natural product, it's not a can of Pepsi. If he can prove to this vendor they are fake, I would expect any legitimate business to refund the product.
third - he raised 4 issues with this vendor previously, as recently as two months ago......and he still went a made a $2k+ purchase of the most faked cigar on planet earth? I mean, some people's greed is just too much for logic to contend with. The movie Boiler Room comes to mind, get a whale on the phone and their greed does the rest, they can't resist giving up their kid's college tuition money for the chance to see more dollar signs.
Every Cohiba I own was bought from Rob right here on FOH. I sleep like a baby at night.
