Hollard Gave My Car to Unqualified Technician

Hollard gave my car to panel beaters that did not have a technician to fix a Mercedes Benz, needless to say that my car has more problems now than before it went in. All that needed to be fixed was my grill and radiator. It failed testing 3 times after their attempts to fix it. <br> <br> The car came back with funny sounds when I accelerate, the technician sent to check my complaint said I quote \that's a worrying sound\". Yesterday after work while driving in the rain I discovered my wipers aren't functioning properly, the rain sensor is messed up. Hollard has not even contacted me to tell me what to do now, despite my efforts of trying to get feedback from them.<br> <br> Hollard my biggest worry now is what else is not working that I will pick up only when I need it, like properly working wipers in the rain. Will I live to tell the tale? "
