A few areas have small discounts for seniors. Since Comcast's reps hardly ever know about them, it's probably best to check with your local government Franchise Authority. Contact information for that Authority should be printed on your Comcast bill.
There are also a few areas that offer Internet Essentials for seniors on public assistance -- see https://www.internetessentials.com/Seniors.
I can certainly check and see what we have to offer, can you verify your account with me? To protect the privacy of your account, please send me a private message verifying your full name, street address including city, state, and zip code (and apartment number if one is associated), and the full account number or phone number associated with your services. To send a private message click on my name, then click private message me.
