The customer service is pretty great overall, I am just really disappointed in the way things were handled at my last visit. I went in for a car service, I was told it was only going to take 1.5 hrs so I decided to wait it out at the center. The service took about 4 hours! They only changed my oil, air filter, tire rotation, and checked brake fluid and somehow ended up charging me $500+! I am never going back here because not only did they up-charge me for parts but they wasted my time. It should not take 4 hrs to do those things.
