Avoid risk of contract termination by changing insurance?

Hi, today I received a letter from the insurance company, which said that my insurance contract became conspicuous because I was smaller than SF3, and had two or more damages in the last 24 months (a self-inflicted accident in 2003, theft of the turn signals in 2004 and an attempted theft of the car in 2004 – i.e., I can only do one thing for it). It was an extrapolation that I paid about 3000€ in 3 years but had to be paid for 500€ damage. Therefore the insurance now wants to increase the partial cascade to 1000€ SB or terminate the contract. Since the contract runs on my mother because she gets it on better terms than me (open service), the question now arises whether it would be useful to terminate the insurance and to conclude a contract on my name with another insurer – with the ulterior motive that the pre-damage then almost disappears. I would start again at 140%, but that’s for me After all, rather than taking the risk that the contract will be terminated next time, and my mother will have problems with car insurance in the future. Here, however, the question now arises whether this also works as I thought it would, or whether the insurance companies will ask themselves beforehand whether the car is “pre-loaded” with other insurance companies. Does anyone know something specific? Greetings, Slaine
