Momentum never took my vehicle registration number

I am livid!!!

On the 31st of March 2021 I needed new insurance I sent through my request to Momentum. I was assisted by one of their consultants. I accepted the offer and gave my details. My policy to date does not have my car registration number, now I have been trying to call(THEY NEVER ANSWER THEIR PHONES IF THEY DO THEY HAVE RUDE SWITCHBOARD AGENTS) to ask them how do they debit me for 2months but they don't know which car is covered? Their app does not even give an option to do that. But when it's time to claim they will say I cant cause they don't have vehicle details OF WHICH THEY SHOULD HAVE BY THE WAY cause that's what you're trained and hired to Don't first thing before you cover you get the vehicle details to the T. Now they are getting my money while I'm here covered only by name. They don't take me serious and the fee I am charged is also ridiculous considering that I am over 30 and married or insurance goes down by colour?

I'm really irritated and ****ed by this
