Bought a Newegg motherboard, never used it then returned it still sealed. Newegg got the motherboard and rejected the return. They said it was opened and a pin was bent. They claimed they shipped it back and refused to refund the money. They wouldn't give a tracking number. The board never arrived.
Later Newegg ended up realizing who they screwed after Gamers Nexus posted about it on Twitter then they fell over themselves to both refund the money and they shipped the board back.
