Dude. so we took our truck there to be serviced on a friday morning before a trip to the snow in utah... basic diagnostic, oil change... that kind of service.. we were told it'd be done that evening and they'd give us a call when we could pick it up. so my husband tells them, please call us tonight... we need the car tomorrow morning. they call us around 4:30 and leave a message on the answering machine to say they were almost done and that they'd give us a call when we could come and pick it up.. estimated a time of 5-530. we weren't anywhere crazy that evening since we were waking up at 3am to drive to utah, so there was no way we could miss the call... 6:00 comes around and my husband decides that it's time to call them. no ones picks up... we live down the street, it takes like 2 minutes to get there in our car, so my husband drives there at around 6:05. they close at 6 so it would seem that they'd close shop around 6:15-6:20 just to get everything locked and cleaned up... they were gone. no one was there.... they don't even have an answering machine, probably cause they get yelled at to much. when we finally did come to pick my baby they weren't as apologetic as they should have been. i had my husband demand a percentage taken off for no coming through on their end.... they gave us 20% off and a coupon [that you can get in your mailer] for our next visit. unfortunately, their will be no next visit.
