This is an absolute scam with no customer service when you are dealing with people’s money. I previously sold two bikes without issue on the site and recently sold a much less valuable third. The buyer claimed shipping damage (bent derailleur) but in his report alleges that the damage occurred after he had built AND RIDDEN the bike. Anyone who knows bikes would have noticed a bent derailleur immediately and reported it. He clearly crashed or did not build the bike correctly and is trying to recover money. They have still not resolved the issue and it has been nearly a month and they are withholding payment (about $2000).
