Car service city wadeville branch

Ever since I sent my car for service at the wadeville branch, it has been none stop problems ever since, within a period of a month, I experience problems. The second last time I sent it there for fixing, they didn't fit all my pipes, battery loose on the terminals, timing belt fittings skewed, engine oil leaks, car idling and I was given back the car as if it is fine. I have sent the car back three times already and still have problem, it has broke down again today. I am exhausted and financially drained because of their incompetence.
