AutoNation Honda Spokane Valley

I purchased a 2004 Ford Excursion from the dealer on 2/7/2015. The transaction went smoothly, albeit, they need more closers on staff to provide a less than 4 hour total purchasing experience with 2 toddlers and 3 other kids under 8. The issue that I am having is that I repeatedly have called to have a part installed that was promised to be installed at closing, and they NEVER call back, except when I made a phone call to the general manager; I get a call back, and they order the WRONG PART, even though I specify in photos and emails the correct part to order. we are going on OVER 10 WEEKS since we closed the deal, and Autonation Honda has not made good on installing the part. Also, I have called to request information on where the windshield was replaced so that I can have warranty work performed on the seal that has separated from the top of the windshield, and THEY NEVER CALL BACK! Am I sensing a common theme here? Autonation markets itself on customer service and loyalty. This is my second Autonation purchase, and I want the general manager to make it right, not another ten weeks from now, but a phone call in the next week, is that too much to ask? You can find me by the vehicle type and year and sale date at the top! Just give me a call!
