Breakpads falls down

It was on the 09 August when I took my car Honda Fit at Honda branch pinetown to check it as I was feeling little bit noise when I'm driving it. They lady who been assist me with service told me to pay R850 just for consulting. I paid. Later she call me and told price is R20.000 for fixing a car include labour. A car is need 1 Stud R80, 2 wheel nuts R76, 1 front brake pads R 1912, 2 front brake discs R 1876, 2 rear wheel bearings R2524, 2 front rods R1294 and 750 labour. I told them to replace all the parts back. When I got money I will come back. Since that time if I'm braking is like something will drop down. I been patient driving with this problem. After few days since I come there someone phone me and ask when I will bring a car back for all this parts. I told her I'm not gonna bring the car I was just want them to check what's wrong with it as is had fun sound as I suspect bearings. So I will buy parts when got money. Today when I'm driving it was worse when I break. Within a second breakpad falls down. That's shows me well they didn't replace all the parts properly. Normal breaks have that hooks for holding breakpads. Nor matter breakspads can be finished I can falls down. It should touch disc. Why they didn't replace my parts well. Is the way Honda want me to come back as soon as possible. It's scary if also big companies like Honda act like fly by night. What if this pads falling while I'm on the road #disasterhonda pinetown. ***** company. I'm to check point for this case and open them case. I need Honda bring back my key breakpads. I bring car there because I avoid bush machenic.
