Terrible work quality

I sent my car in for repairs, For wrong fuel in the tank and only that. Repairs were quoted and I accepted. Problem was the time delay it took them 2 month's to fix the car.(quoted 20hours labour to fix, take into account a week or 2 for parts delivery this was way too long) Eventually I received the car. I collected the car and was informed to bring back for 1000km oil change Then , next day found leaking oil and leaking petrol and leaking water. Took it back, to them, it took 4 days! claiming the car takes long to strip. After forcing for them finish, I collected my car on the Friday. And was informed that now water pump has become faulty, for a car that was just "rebuilt " and been parked for 2 months, the water pump isn't working??!! ,it never had water pump issues,didn't believe it and am not taking their nonsense. Again my car is leaking oil at the top. What chance is there of them fixing correctly? a few days later, the heat shield under turbo was fitted losely(it was rattling hard), and hoses to the water pump not tightened(confirmed with another mechanic), and I still have a front bolt for the mag, that they lost. Am I really ever going to take my car there? Never, and I suggest others not to send their car for repairs. I have taken my car to another mechanic who fixed and stripped the car in a day. These franchise workshop are not working to an ethical or fixable standard when it comes to repairs. I suggest to people never to take their cars for repairs.
