28 August i was involved in car accident and my car was damaged due to negligent from Group Five unfinished road works in clermont near pinetown it was me and another car involved i informed group five about this and they knew they were wrong hence they was no sign and they left the road unfinished , i reported my accident to Safety Manager Chris Govender and he advice me to get quatation how much damages will cost so they can assist me i sent him quatation and he told me he will sort with insurance company, he never gave me feedback i was the one who was calling him asking for feedback this is very bad i was about to trade my car in with dealer and now i have lost that deal due to long waiting claim approval big company like Group Five should be able to assist with good customer service , they dont care about us
