Poor workmanship and no follow up

Approximately 2 months ago, Lynda Schutte brought her Hyundai i20 into the Farbers Montague Gardens branch for superficial repairs, due to accident damage sustained. These repairs were carried out by Farbers over a period of approximately 2 weeks where after the vehicle was collected. On the first occasion that she drove the vehicle outside the bounds of Century City the vehicle overheated on the highway and was then taken into Hyundai Milnerton on the Monday. Hyundai advised that on inspection the fan cable for the radiator was unplugged which could only have occurred during panel beating in your workshop - accordingly after some back and forth with Bronwyn Brisset (which took more than 10 days) Farbers accepted liability for repairs and granted approval to Hyundai to proceed. Hyundai carried out works and the vehicle was returned to Mrs Schutte on Monday 20 July - 6 weeks after the overheating incident. Having had to rent a vehicle for 6 weeks we are seeking compensation due to Farbers poor workmanship however Raydon is avoiding calls and we can't reach anyone for answers!
