Autostream Car Care Center Baltimore

I brought my car here to get it fixed because it was overheatingThey've repaired the overheating, but made it so that my car did not start consistentlyI had it towed back to them the day after I took it home and they kept it another week and gave it back to me without figuring out what was wrongI had another mechanic diagnose it and he told me that it would cost me another $1000+ for him to fix what Autostream messed upSo, I took it back to them and they returned it to me a week later with the exact same issue of it not startingThey are denying that they caused this problem, but this is not an issue that my car had before they got under the hood
