Do any of the other manufacturers use YRC Freight for returning of core parts to manufacturer? I'm beyond done dealing with these people.

Everytime you give them a "confirmation" number which obviously is a usual number that doesn't mean they are coming to you. Everytime I've called them, I get the same old song and dance, we're so sorry and only 1 liftgate truck in your area today but your service hours don't work for them. Any other input otherwise I'm ready to send my Nissan FOM and email from hell.
Thanks again guys.
