Crazy shit happening in my VAC

I have vedic maths as subject and owing to exams of sem3 classes were online , during the class mam was being muted again and again upon which she started shouting on us and saying "go to bloody hell" . And then in the next vac group , a student asked mam aapke toothpase mai namak hai ? And then mam started shouting on him as well , she called the whole class "bastard", go to bloody hell , etc.

Should we mail the admin relating to this ir should we text mam an apology letters?
