I HATE PSA customer service

I ordered a stream light TLR-7 HL-X. Package got delivered and opened it up and it had a Holosun red dot sight in the box. I call PSA the minute I notice the issue and they inform me that streamliggt shipped the package to me, not PSA, and I’d have to contact steam light to get it resolved. A) that’s just shitty customer service. B) why the fuck would streamlight ship a holosun?

Edit: called streamlight and they don’t drop ship single lights, only larger orders and the SL customer service guy assured me they definitely don’t distribute anything holosun. I called PSA back and after I told them what streamlight had said, they changed their story, and that they just pulled the box off the shelf from the manufacturer and put a shipping label on it and sent it to me. Which still doesn’t make sense. When I asked what the way forward is, they said I would have to order another light, which is now out of stock. They told me I would have to wait til they were back in stock and repurchase and send back the holosun.

Fuck PSA CS.
