Smart Auto Electrical & Air Conditioning

Have used Smart Electrical three times so far … Dallas has been so very helpful with advice and all aspects of our car and caravan electrics

He talk to me the problem is tube is dirty? So it should be clean up. Then I paid $200 for cleaning tube and change filter. But the next day my car's air con doesn't work again. I take back to them the car they said fan should change cost $800. But fan was working before I take the car to them first time. Engine cover also is broken after service. But they said not their fault.
I am not happy. Wasting my time a lot.
