Mavis Discount Tire

Mavis store # 188 sold us 4 new tires with pressure sensors on jan. 12 2021 one sensor kept losing it's signal and they said the problem was with the truck, not the sensor and they refused to replace it saying I should have chevrolet look at it. On jan 27th. Joe basil chevrolet replaced the bad sensor. Problem was not the truck, but it was the bad sensor mavis put on. Mavis owes me $50.00 plus tax for the bad sensor they put on my truck. They also charged me $10.00plus tax for tire disposal fee. I took my old tires with me when I left. They did not dispose of anything from me. I want $60.00 refund and they can have their faulty sensor back. They refuse to answer my emails I have receipts. This was for mavis invoice # [protected]
