Home tech visit by very unprofessional person

The Xfinity tech that came to my home today was very rude and unprofessional. Was extremely rude to my elderly mother. Of course there is no way to report this behavior and this tech will continue to intimidate and act unprofessional with no repercussions.
This is exactly why people are leaving Xfinity in the drives
I will gladly discuss with a representative, message me.
