Ordered a nearly $1,000 part with 2-day shipping so i could get my truck on the road. They called with an automated message late the next day notifying me the part was no longer in stock and i had two options; cancel and wait a few days for my $1,000 to come back to my account or pay $500 more to get a substitute part... no one to talk to about it, no form of real customer service, no form of compensation even in the form of shipping to get the more expensive part to me faster.
