I once shipped a single Rec to LA and the headshell cracked. I was pissed cuz I packed it super solid. Anyway, buyer wanted to keep the amp cuz it worked, so I he decided to drive to Mesa and told me a new headshell was $300. I paid him $300 instantly and then dealt with the UPS claim to get reimbursed my $300. That's how it should go down.
If he didn't give you the uber back, he shoulda gave you the money from the uber sale. And Jim from Scumback is right. Here we are April 15th, that is way too long, and for you to see NAD threads in the meantime woulda made me freak. Patience is virtue, but so is honor. Shoulda been taken care of as quick as possible.
