Re: Update Your Payment Method with Xfinity to Keep Your $10 Discount

I received an email from comcast :

  >  Just a quick reminder: to continue receiving your full $10 per month automatic payment and paperless billing discount, you will need to update your payment method to a bank account using an account number and routing number no later than March 24, 2023. 

But I am not being reminded since I've not been told about such a change.  Is comcast going to begin charging more for customers who have been using auto payments with credit card for years?  Where is this mentioned?
