Traffic speeding ticket: Did not get anything in mail. What to do? Please help. Hello,

I got a speeding ticket on 880-N on 2/6/21, and the police officer told me that I’d get the fine-related stuff via mail in a month. It has been two months, but I still did not get anything. 

And in the ticket, it says that I should pay by 4/15/21. 
I’m panicking now. What to do? 
I have been calling the court for two weeks. I wait, wait and wait and finally, it asks me to send a voicemail. Nobody got back to my tens of voicemails.

Will my license be canceled or anything similar if I don’t take action by 4/15/21 as it says on the ticket?? 

This is my first traffic ticket in the USA. So please don’t mind any stupid mistakes.
