Malfunctioning Brakes

I recently took my vehicle to "East Coast Power Steering and Brake " in pietermaritzburg ,for the rear brakes to be fixed on my vehicle.Upon on collecting my vehicle I found the brakes to be in a worse condition than it was before , I was informed by one of the admins that it's normal to feel like it as the brake pads needs time to settle in and that I should bring back my vehicle again for the brakes to be reset.The day after ,the mechanics reset the brakes ,and it felt fine , until I got home.The next day it felt worse than the day before.I didn't bother to call them again, as it is a waste of time,and fuel to drive to them all the time.Now I drive a vehicle with defective brakes and a handbrake that doesn't even function properly.My vehicle's handbrake worked 10 times better before I went to them..My wife also took her vehicle to them for another type of problem, as our mechanic advised us that they'll be the best option to repair it the problem on her vehicle, only to be told by them that there's something else wrong , which there wasn't...I've spent a lot of money on them to get my brakes working like new again, which isn't the case, and I refuse to go back to them as I fear they might find something else wrong to use as an excuse , and end up paying even more for something that wasn't necessary to be fixed , and end up with a car that worse off than before...I WON'T RECOMMEND"East Coast Power Sterling and Brake" in pietermaritzburg to anyone at all , for their service is not satisfactory
