Took my car in for an oil change and they filled my oil up too much which then my car Dealership Subarbu noticed and notified me. I then had to pay Subarbu for an oil change because the mechanic didn't fully do his job. I brought in receipts and all they did was offer me a free oil change, no thanks. I'm no longer interested in your service and I should've waited for my mechanics availability to open rather than stop in.
