Wisconsin Muffler, Tire and Auto

I took my car to them bc the check engine light popped on. I have taken my car to the Lisbon location several times about my check engine light. After spending the money to "fix" that problem the light came back on every single time. (a total of over 6 times) I kept taking it back because I paid for them to fix it & they needed to fix it. This place is a total rip off! They fix one thing on my car then tampered with other things. I know this because I had a previous diagnostic done on the car beforehand. Just recently took it back because what do you know..Yeah the light back popped back on. They keep resetting it instead of fixing it. This has been going on for almost a year & they do it to females on a regular. They have been threatened with physical altercations because their service is well, bootleg. Please don't take your car there. They mechanics need to be investigated & they need to be shut down.
