Supaquick lydenburg playing with people's lives

Supaquick in lydenburg mpumalanga is the worst I've ever seen. They have fitted 2 new front shocks on my vw amarok. They didn't tied up the bolts again properly and i almost made a big big accident due to them and then they refused to take responsibility for their actions and the management told me they don't have any guarantee on Labour. O I just wanted them to at least pay the towing cost i had to pay of R7500. But nothing they ignore me flat even supaquick head office ***
