Renew-it sandton poor service

Poor service I received, PMD towed my vehicle for a minor front damage, 3 weeks later they called and told me that my car is ready I can come collect, when I got there, they told me that everything is fine i can take the car, on my way home driving at freeway and the bonnet just flipped opened and hit the windscreen I couldn't see luckily I managed to pull aside only to find that those guys didn't mount back the bonnet clipper. Towed the car back they never apologized nor take my case serious, i am the one who always call and ask for an update, they always promise they will get back to me but empty promises, asked for courtesy car since its their fault not mine but they keep saying they will get back to me till now. This morning i called again but they failed to give me a proper feedback.
