Bad car insurance

I an in incident in August 2019. First momentum sent my vehicle to these pathetic panel beaters called black diamond which made my vehicle in worse off condition. Then I sent my car back. Net assess had suggested rennies. And I was happy. Until momentum still has my vehicle for 4 months. With no vehicle before Christmas I keep calling the agent Nomthandazo Mtatsi. And leave messages but she never calls back. Until I get my car back in proper condition I suggest no one take momentum car insurance. They are absolutely useless
