worst business award goes out to mad diesel performance, and the owner, Matthew Dunavent I don't even know where to begin on 09/15/23 I ordered an exhaust/tuner/air filter for roughly $2100. He said there was a problem with shipping I said OK I'll wait a month goes by never got back to me never responded so I filed a dispute. All the sudden he calls me and says you can come in and pick up either your parts or your check for that amount if you cancel the dispute , I drive an hour and a half to the shop I called and canceled the dispute on speaker in front of them after I cancel the dispute he literally told me that he cannot release my parts to me, nor can he release a check to me. I told him that I was gonna reopen the dispute he said unfortunately, you can't open the dispute after you closed it little did he know that, my card provider stated otherwise so now I had to reopen the dispute people please before you buy parts or buy anything from anyone look the company up and see if they're reputable and if there's any ratings because this place is unbelievable never in 1 million years have I ever thought that I would have to go through any shit like this. I bust my butt off for that money for him to pretty much laughing my face. This is a shit business, and I would not recommend it to anybody ever. read more
