I bought "Purple Haze" and I want to know what strain it really is

Hey, I bought some so-called "purple haze" from a friend of my friend. I really don't know him much, but he convinced me to pay $30 for a gram of purple haze. Where I live, $20 is the price for good shit, and so I did some research. Apparently, people call it purple haze to make it sell better and for more $$$, and that the strain has been gone for a long time.
One of my friends ended up buying a quarter oz of it, and actually got to buy it for $105 instead of the acquaintance's asking price of $130. I figure this kid is either trying to scam people or he just doesn't know the difference. I think he is trying to scam people. He's now selling for $20 a gram, but I want to ask him what the strain really is. It was really purple when I looked at it. First time I ever saw purple weed, even though I know there are purple strains. It was potent, but I hate getting lied to.
What should I say to him?

 

I just wanna know what the real strain is.

 

I'm not trying to have you guys distinguish the strain. I wasn't that clear though. I just wanna know what I should ask him. I don't care that I payed $30 one time. I can afford to do that once in a lifetime.

 

I heard that purple haze has been gone for a long time, as in the strain does not exist anymore.
People use it as a way to sell weed faster and/or overprice it. I didn't care, I was in need of some stress relief. I can buy the same shit for $20 now so it doesn't matter. I think he's new to dealing.

 

I learned from someone else that Purple Haze doesn't exist anymore.
