Is the following review positive or negative?

I've gone to this specific location a few times out of convenience, but not any more. My most recent trip was mostly a complete waste of time. I asked for a simple balance service, and they only made it worse. The only thing keeping me from giving one star, is the fact that I didn't have to pay (rightly so, as they mounted the tires/rims to begin with). The store on 99th and McDowell is far superior in customer service and technician quality. They properly balanced my tire and made the problem go away. Turns out a couple of wheels were more than 2oz off... maybe the Dysart store needs to calibrate their machine.
negative
