I was issued a new lower priced plan after 1 1/2 hours on the phone with a Filipino and am still be charged the old plan.

Is there a way to send an email to Xfinity? About a month ago i switched plans, and i got an email confirmation from them. I would like to email Xfinity, to show them the plan change, to prove that they made a mistake. It seems to be impossible to find an Xfinity email address on their website. I was also told several times by the Xfinity Filipino service representative that I was eligible to go to the store and get 2 different discounts that he wasn't able to offer on the phone. One for military and one for senior. I asked several times about that and was assured that it was a legitimate discount. I spent an hour and a half going to the store and back to find out that that was a lie. The new plan I was given is $48 less than the old one and I have the email but I need to send it to them to prove it.
