Momentum insure is ****

I called momentum insure to remove a car and to get a quote for a new vehicle. My dad is the main policy holder and has been for Years and I, as his daughter, was able to load my cars onto his policy which Momentum allowed since 2019.

Today when I called momentum to remove the car, I am now told that my cars that's registered under my name cannot be placed under the policy of my dad's, that's been active for years! No communication from momentum, just the fact that if I were in an accident or something worse, they will reject the claim.

This is pathetic. What the hell is this?
