AutoNation Chevrolet Valencia

Sad that I should have to do this. But here I am non the less. I picked up my 2015 Silverado on the 27th of October Last Year, after recall and warranty work. It wasn't until the next day that I noticed (2) Plugs missing from the "Factory Installed Bedliner". After several attempts I finally talked with the Service Writer. I sent him pictures including one of the missing Plug I removed from another location on the liner. It had a Part Number. Seem's easy enough, order the part. But that's where everything just stopped. I got some story about that p/n not being in the system, and that's where everything just stopped.No call backs no more communication. I contacted Chevrolet, and the Dealer is Blowing them off as well. P/N 23458540 is available all over the Internet, but going the distance to take care of a customer is not something AutoNation Valencia seems to care about. I might add that they left Dirty Handprints on the Headliner and Sunvisor, and the Seat Cover on the back seat was removed and left balled up like a pile of trash. I did purchase the truck from them and the had no problem sending me multiple emails and letters to continue the extended warranty. To sum it up Take Your GM Product somewhere else for service.
