Worst service received from any company, 4 weeks to replace a windscreen and a vehicle key? I am driving around with windscreen thats totally cracked. Claims consultants provide such poor service, I even expressed my unhappiness via email to a manager Tanya Venter, the response I got was that a glass company has been appointed to assist me. Wasted over 30mins of my life on Friday trying to reach someone? Finally get through, the consultant says she will check my claim,after holding, the next thing, im through to the towing department? What happens if I'm in a car accident? How long will it take for your company to get me back on the road? 3 or 4 months? After spending all my minutes on hold, consultants say they cant dial me back?
