Terrible Service Received from Momentum

Hi All totally disappointed with the service received from one of the consultants working for momentum pertaining car claim asked her to call me back 3 times today and left her an email still no call,My complain seems unimportant to her considering that she hasn't responded to me I was involved in an accident almost a month ago and had logged a claim process with renewit sandton is revaulting had to phone constantly to get updates at the end of 30 days term for hired car is only when the assessor is assessing the damage on the car....what am I to do as my work requires a car.I am stressed and had panic attacks when premiums find way to my bank account with ease what is one to do with service this horrible does momentum even care what I am going through right now?I don't get to choose a panelbater why is it my cross to bare when they are not finished in 30 days?how do I take my children to school when my car is still not fixed let alone car hire expired I am shuttered and lost for words
