Dent Bros. Awful job, gave wrong contact information Chino, California

So i was on my way back from the store when these three guys come up to me and ask me if i wanted a dent in my car fixed. I said no but they where extremely persistent and annoying so i decided to just say ok since they kept lowering the price and where bugging me. They did the job which looked fine at first. They put some sort of wax on the fixed dent after and so i paid them for the job. I asked for a business card in case something went wrong. They told me not to remove the wax 40 minutes. So i went home thinking i got a good deal. After the 40 minutes where done i wiped the wax as instructed. The dent was gone. The only problem now was that they cracked my paint job and the dent was replaced by nasty looking bulges. Now it looks even worse then it did when it had the dent. I tried calling them but the phone number on the card they gave me was some guys that said i had the wrong number. I tried calling again more than 3 times in case i didn't dial the number right, but the same guy answers saying that i have the wrong number. So use caution if anyone comes up to you saying they can fix your car dents. Especially if its three guys in a white car. I wasnt able to get the make or model of theyre vehicle, but i did get the first few numbers in the license plate in case something like this happened. "6k0j" So use caution in dealing with these crooks as they will make your vehicle worse and give you false information
