Koons Tysons Chevy GMC

Dealer replaced the rear left wheel hub and bearing along with ABS sensor. Repair cost was $800.....yes wooowwww..thank god i had Ford extended warranty only with $100 deductible. They didn't even try to help me since the car was 51k and out of warranty. I had a coupon for $40 from the dealer (Tyson's Koons) and they said since I am covered by an extended warranty and paying just a deductible I cannot use the discount coupon. When I told the service advisor (Steve) all the trouble I went through with this car (48k radio replaced, 49k water pump replaced) and asked him politely to call the manufacturer and try to cover this repair under the GM warranty, he looked at me and said " did i sell you this car?" What an answer......shame on these kind of people and companies....AND I told him yes you did, since I bought it from Koons Ford, and took it to be serviced at Koons Buick.....This is my own extended warranty and I am not stupid, I paid for it from my own pocket . They are sooooo greedy... I can take my car anywhere I want and get serviced and Ford warranty will pay the repair cost. They all see you as green $$$$$$, customer satisfaction is zero!!!! Even Buick customer rep contacted me through Buickforums.com and offered assistance but it was couple days later than I took my car to the dealer. I knew they could have helped but instead servise advisor Steve insulted me. To be honest I didn't believe all the 5 star reviews here !!!!
