Windward Audio sold me 1 product, and I find out it wasnt what i bought Kaneohe, Hawaii

I'll make this short. went to these guys little over a year ago for a DVD player, amp and speakers. Basically paid over $1000. I was selling the car this week to a guy and told him about the stereo and how the speakers and everything were top of the line. so he wanted to check it out as he said it didn't sound right, and we opened up the back speakers only to find a totally different brand of speakers that cost 1/3 of the speakers I supposedly paid for.  I mean it was embarrassing enough getting ripped off by Windward Audio in front of a guy who was thinking I was lying to him.  You can't believe how pissed off I was.  I thought about what happened and remembered When i picked up the car from Windward Audio he didn't give me any boxes, and when I asked about my old stuff they said they threw them all away. 

Don't go to these guys, unless you see them actually installing everything.
