Well I don't think it's vapor's tongue. Because you said others tried the juice and found it tasteless.
I would let the seller know that. I am assuming you aren't doing anything suddenly strange with your setups, so I am left with bad juice. Maybe the bottles are elderly? Can you see if there is any date on them? Exposed to too much heat/light during shipping? That could be a possibly I guess.
The varieties of eliquid are completely endless. I'd suggest some small "taster" sized juices from a few reputable companies and see if you find anything you like before committing to a large order of one flavor or another. It will take longer but ultimately you will find "your" juices that suit you.
Good luck, and if it were me I probably wouldn't give up on a refund quite that easily, either.
