Where can I go to get some service?

[vip808]

I just got my truck serviced at Pflueger Hummer in Honolulu and I'm furious!
I went in to get my Hummer seat recall fixed, have my one year service (minus oil & air filter), and have them find out why I was getting a "service 4wd" alert.
The first time I had them service my car was because the PCM went out.. i lost 3 days of work because they had no loaner.. and they dinged my right door and stained my headliner.
Today they did the service (minus oil & air filter) couldn't figure out the "service 4wd" code co359, and here's the kick in the ass.. they dinged my left door and left the stain on my headliner!
they told me they tried their best to protect my truck then took it to their body shop and buffed out most of the ding but left swirls on my door..as soon as i got home i started working on the ding and brought it down to two little specks.
My wife was also furious and told the service guy that her Honda gets better service from the dealer and her car's a piece of junk.
I hope someone from GM/Hummer reads this because I want to know where else in Hawaii can I go because their service dept here sucks like hell!!
