Down Range Firearms Training

I bought a Groupon back in October for a basic class for 2, and signed myself and my husband up for the first available class, which was supposed to have been this past Saturday, ½/​15. I didn’t mind the wait because it was a good deal and we were in no particular hurry.
Fast forward to this past weekend. We show up to the address in Matt’s email signature, which is also on the website, only to find that there is nothing there. I checked the Groupon, which showed a different address, so we went there (luckily we were early). There was a firearms school there, but not this one. No one at the gun store on site had heard of it, either. We called the person whose card was outside the other school’s door to see if they were affiliated and where Matt was. The guy said he gets these calls all the time — said Matt never worked for them but used to work upstairs, but last he had heard, Matt had moved to Oklahoma. Lovely.
It looks as though maybe this did used to be legitimate, but it sure doesn’t seem that way anymore.
