Mavis Discount Tire – Revving engine

I went to Mavis at 74 W Westfield Ave., Roselle, NJ 07204 on Jan.23,2025to have my back brakes checked, no repair was done and my car was in the shop for 1 hour. My fob key was taken off my key ring and put in the passenger seat, I explain to Anthony that the very slight touch my car is on and it is revving for a long time, I did not have this problem when I went Mavis only when I left Mavis. I been owner a car for 50 years new and used and I Never experience this problem. Ms. Perkins at [protected]@gmail.com
