Motor Vehicle Claims not attended to

I reported the car accident on the 29th April on the Momentum app and the note I got is that Momentum will call me to finalise the claim,On the 29th April I followed up with the call and the lady assisting me took down my details and told me that an agent will call me back.On the 30th April same thing happened, they took down my details and never called me back..Again on the 3rdvMay I called and same response that an agent will call but to no avail.I can't use my car because the front bumper is damaged and I need it to be fixed so that I can travel to work sites regularly,I pay my premiums every month but I am now be taken from pillar to post when I am trying to claim
