Mufflers 4 Less

They charge me 400 for bar rotaries and brakes which I got all this did like four months ago from another shop . He gave me the parts to take to mufflers for less in South Holland to get credit because I had a warranty on all of the parts. I go back to the shop in South Holland showed them the parts and bills.. guy said nothing was wrong with my front end bar or rotary because he just put it on a few months ago.. And that I was ripped off that they charged me for parts I din't need. I went back to the shop to tell man he was very rude said take him to court which I Weill be doing. Ladies Seniors or ppl that are in a rush and desperate don't go here. And the wait was four hours and my van rides about the same without the noise
