Lost income

I logged in as usual to my Zoom account to run a class. The class is an income source.

There was a message saying unusual activity on unfamiliar device ( there was none from me) and asked me to verify via verification to my email account.

The verification code was never sent no matter how many times I asked to resend. 

By the time I saw that I could log in via Google it was too late to run the class and I lost a considerable ammount of income.

I'm confident it was a hiccup on Zoom's part.

Am I able to receive compensation?

I have not been successful in sending a complaint to Zoom. It's a mystery to me how to do that?
