UPS kept my Bose and put the delivery info from another package (from 8 days later) onto the Bose and tried to claim they delivered it. When they couldn't come up with correct delivery info, they pulled the legitimate tracking info from their website.
Lucky I made copies of all of it and submitted it to Bose, who agreed with me and sent a replacement to my appartment office and it was signed for.
2 months later UPS was trying to say the second delivery was the first delivery.
I told them I had possession of documentation & would contact the FTC if they continued to harass me. They stopped.
