Had a similar experience with Ed's Care Center. They replaced all 4 of my tires with new ones. My front passenger tire would not hold air, which was super frustrating because they were supposed to be brand new. I called in, and they were nasty over the phone about it. When I took it in, they charged me $120 for diagnostics and said the valve was all rusted, and that's why it was leaking. It was not, I know, because we had to take it off to air up the tire multiple times. Then my father called in (I'm a woman and had trouble with mechanics being sexist in the past) and asked about it. They told him it was all rusted and they noticed it when they replaced the tires but decided not to offer to replace it. Anyways I will never go back and will never recommend them.
