Goodyear

I being charged for a part that was put on my car that I didnt need. I am very up set. I used my Goodyear credit card and tried to disputed the charges and the owner is not being truthful about the situation. I need some help. They put the wrong part on my car and want me to pay again to fix what I came into the shop to get fixed in the first place. I have called the owner several times and he would not come to the phone and left messages and he will not call me back. I need help please. I do not have any money to waste. I went in there thinking I would be in good hands because of the Goodyear name but I was wrong.
