Mavis Discount Tire review: Oil change

I was over my oil change mileage and was aware, I went to get my oil changed and when I got my car back my engine started making a very loud clicking noise and started losing power after 40 minutes of getting it back and the oil gauge was still popping up on the dash still. My car was not doing this prior to the oil change. I had called them explaining my car was not doing this or even was close to losing power until they did the oil change and I retrieved my car back. Not even 40 minutes later it sounded like my car was about to blow up, they told me to bring it in to look at to see if it’s their fault or not if it was they would resolve the issue. I took the chance and drove the car there and sat across the street , I watched them pull my car to the back or wherever and not even two minutes later pull it back out to their parking lot so I’m fully aware nothing was even checked because it’s impossible to put a car on a lift and check it within a 2-3 minute time span . My cars now been sitting there for 10 minutes, I’ve received no call as I believe they are waiting to make it seem like they checked it little do they know I’m sitting across the street at subway watching them and watching all this happen. Meanwhile my cars the only thing I have because of my current situation of being homeless it’s been my home and the only thing I’ve had to even be able to keep even a little bit of hope for anything. Now I have nothing.
