Shocking Mechanic Work

I took my Hyundai Tucson in for major engine repairs it was a non-runner, they completely failed to repair my car, They kept misdiagnosing the problem and asking me to buy parts but to no avail, its a shame. I bought a secondhand engine and still the car makes weird noises, car braking ABS system was working before I took the car for repairs but when I went they told me it wasn't working I was very shocked, had to eventually tow it home because the car couldn't brake ,My word of advice, only take your car for a minor service, anything bigger than that take it elsewhere ,they clearly dont have time to waste on major repairs
