Does Xfinity have an e-mail address for customer service?

I have an issue I need to have resolved, the name on my Xfinity mobile account is incorrect, it's in the name of my dead mother who's been dead for 3 years (She was dead for 1.5 years when I got the account) I despise using the Xfinity assistant or talking on the phone with a rep (I can't understand them), I would like this resolved via e-mail, please get back to me.
