That's really bad, and I too have had a very similar situation through Reverb. The seller didn't respond to anything after I purchased an item, so I contacted Reverb. They said they would contact the seller, which I'm not sure if they really did. After 3 weeks I had to dispute through PayPal because nothing was changing. At this point, I tried to leave negative feedback, but it wouldn't allow it. After another month, my money was refunded by PayPal, and the seller had relisted the item, apparently without any consequence from Reverb. So, I waited a month and a half to get my refund, couldn't leave negative feedback, and the seller gets off the hook. What a load of crap. I even asked Reverb to contact PayPal in order to assist with the PayPal dispute process, and they refused. All in all, I've had several transactions through Reverb go poorly (either it never shipped or wasn't described/photographed accurately) and Reverb was unable to offer any resolution or effective support. Either I lost out, or battled with the seller to find some sort of middle ground.
