Horrible customer service and not performing the job

I first took my car in for repairs on 1st August 2022 Two weeks later after after it came .it had exactly the same problem I took it back on the 2 /9/2022 .They told me they will replace the faulty parts I have never received a call from them to update about the progress of the car.Everytime I was informed that they have ordered the part. Today I called and told they informed I can pick up my car and the mechanic would like to have a word with me.The mechanic informed that the part is not replaced.they are still waiting for it but I can take the car because he fixed it.I was shocked because I got stuck on the side of the road with car now he informed me I could take it even though the problem is not fixed.
