AAA Mattress Wholesale

If you’re looking for a mattress beware of being enticed to go to a wholesaler like this one. I live in the East Bay and desperately needed a short term use mattress (2 – 3 years at most). I did a google search of local mattress places, and I stupidly made the mistake to pick this wholesaler to get a cheap mattress because of my planned short term commitment.
First off, this is the listed address on Google but you actually have to call the guy (Norman) and get the address to his warehouse. He says, he’s selling the brands at least half the retail. I think he’s selling overstock or something. The mattresses are organized by sizes «small in the back, big in the front» he says. Don’t ask about a specific brand, he doesn’t know if he has it. He doesn’t know about mattress firmness either.
None of the spring mattresses were the firmness that I wanted. So he shows me a memory foam mattress and tells me it’s a Tempur-​pedic. I’m in disbelief because they’re expensive and I have no idea why they’d be in wholesale but he showed me Tempur-​pedic brochures pointing out sizes and firmness. I kept asking, «this is a Tempur-​pedic ?» (obviously unconvinced) He says yes.
So I bought. Not Tempur-​pedic. I call him on it. He says, «I said it’s LIKE a Tempur-​pedic.» I say, um no, I have 2 witnesses who say you confirmed it’s a Tempur-​pedic after I repeatedly asked about that brand and sold it to me at a price that’s half the retail price of a Tempur-​pedic not half the price of a generic memory foam mattress.
I try to contest the purchase through my credit card company and they say unfortunately they can’t do anything about it. I look at the receipt and lo and behold he writes in «memory foam mattress» as the line item instead of Tempur-​pedic mattress. I’ve been duped.
I’d say this mistake was mostly my fault. I was too hasty in this purchase because I needed the mattress right away. But like a bad twist of fate, his last words to me before I begrudgingly take the mattress home was, «You can go to your credit card company if you want. But let me warn you, everytime someone tried to complain about their purchase, I always win» (paraphrased).
How many times has he done this to customers???
