No window for three weeks

My claim # ********** was approved very quickly getting the broken window replaced however is another story. A three week wait as a minimum. In the mean time I must srive a car in Johannesburg without a rear window ..... what security..... what if it rains..... i cannot even alarm my car as it triggers all the time. Discovery will not give me a rental car so I must drive mine without a window. If it rains my upholstery gets wet ..... thia is not a solution and passing the buck wont make it go away.... Unhappy customer! !!
