Mavis Tire Corporation review: mavis tires put the wrong size tire on my car & won't make right 1

My 20-year old nephew who is away at college most of the time went to Mavis tires 3 months ago for 2 back tires. Two weeks ago, he took the car to Parkertown and they informed him that there were 2 different size tires on the back, one of them was the wrong size and that they had to put the correct size on for legal reasons. He didn't have an option to drive away with the car with the wrong tire still on it to go and show Mavis Tires.Now Mavis Tires will not make things right by giving my nephew his money back.

Not only did Mavis put the wrong size tire on it, they never wrote it down properly - hmm, was that a coincidence? I think not. Whoever is working there obviously can't read, don't know what they're doing and are just disgusting human beings.
Not only did they let my 20-year old nephew drive around in danger for 3 months but now they won't make right by him? What kind of Corporation does that and how do you sleep at night? It's a $100 and you won't make this right? You put him in DANGER for over 3 months, you're lucky he didn't get into an accident.

To anyone out there, I would steer clear of this tire place and all its locations - they obviously don't have a clue. I hope you have done this to someone else and they sue your [censored] after they get into an accident.
