l&j tires and wheels

Purchased two used tires with serious cupping on them. Secondly, my TPMS kept flashing as a fault on my dashboard. Found out that they replaced my TPMS with a regular valve stem and no sensor. I brought it to their attention. At first, they told me to get it reset at the dealership?.. Anyway, they said my sensor fell off the time they replaced my tires. So they put another one on. They should have told me in the first place instead telling me to go to my dealership. I am only giving a bad review because I was met with rudeness, and unprofessional behavior. I cannot bring myself to go back there ever again. If I could give zero stars to write this review, I would. I guess one star will do.
