How to ask forgiveness for hurting people?

I cussed at customer call. I called my mom and before the ringing there was a description about corona virus. I got irritated hearing it over and over again i cussed at it. I didn’t know that call centre agents hear whatever we say until today. I am deeply sorry for my actions. I did it many times in the past. I am deeply remorseful because so many people were hurt because of my actions. How can i ask forgiveness for that?
