Discovery is really disappointing me

While my car sit rotting at the repair shop, I've called Discovery Insurance FOUR times today since 08:00 and on EVERY occasion, I have been told that the person will call me back and has NOT. I spoke to Nosi just now and yet again, she allowed my airtime to run out and still has NOT called me back despite saying that she would. I reloaded airtime and called back again asking to speak to a manager on this occasion and I was placed on hold until the airtime which I reloaded cut off again. I have spent to much money on airtime to get some sort of feedback regarding my claim/vehicle repair, but to NO avail! This is pathetic. My daughter has to be at school next week to write matric final exams and I have no idea how I will be getting her to school! I have explained this to the consultants but they clearly don't care. Sanilisiwe who is handling the claim promised to get back to me THREE days ago regarding my query about the vehicle hire which was omitted and I have never heard from her since I lodged the claim. I am so frustrated and so stressed about this. The staff are of no help at all. Calls get cut and nobody calls back as promised leaving one no further advanced and stressed
