Momentum Short term insurance - Still waiting for my car.

So disappointed with Momentum short term insurance. Accident last year, then they appoint poor performing panel beater company. After more than two months I get my car back with a torn seat (nothing to do with the accident) and various other issues. Then I take my car back to the panel beater myself, because all momentum ever tell me is they will "phone me back" and I have to speak to different people every time and have to explain the whole story over every time. After another week at the panel beater they tell me my car is finished. Yet....nothing done. I did not appoint this panel beater however Momentum leaves me to deal with them, cause they do nothing from their side.... They take no responsibility, no effort. Two and a half months without a car, STILL no car, a lot of airtime wasted, a lot of my time wasted... still waiting for my "call back", still waiting for my car. This review is after I have spoken to STI, complaints, managers etc. Pathetic.
