Terrible Service Received

They were supposed to sort out our bakkie after an accident and the bakkie has been back to them n 4th time and still not sorted. The only time they communicate is when they call to find out why the insurance has not paid their invoice yet. when your vehicle is there then they don't bother to even give an update and if you call and eventually get hold of them then it is one lie after the other. It has been 8 months since the accident and still nothing sorted out. WORST SERVICE EVER
