No cancellation email

I have been with Tesla Insurance for a little over 2.5y. One renewal cycle, and I am on auto renewal, they cancelled the insurance because they couldn’t process the auto renewal as my credit card was renewed.

I tried asking around and they said they sent a cancellation email, but I have no record of it whatsoever. There was some time when I had no insurance. I did not check the app, I did not check for emails as I assumed they would auto renew as usual. During this time, someone vandalized my car. Current estimate is $3k+.

I feel cheated here. There seems to be some sort of technical glitch which I am having to suffer for now.

Is there anything I can do legally here?
