How to CANCEL: Bill increase, incredibly slow speeds (less than 10mbps download, 1 mbps upload)

So, I just did another speed test at 7:16AM. 2.65 Download, 1.62 Upload. I am using my ATT phone now for almost all necessary internet work. And full disclosure, we are both senior citizens and Immunocompromised due to cancer treatment and a blood clotting problem. Any essential items, like food, we need to order online for delivery/pickup. This is a real situation. We are coming from a large metropolitan area with a realistic, usable internet connection. We recognize the limitations of Hughesnet satellite but this current/new inaccessibility is NOT acceptable. It is clear that the slowdown is due to changes in access for individual subscribers who do not fit your new criteria. We understand but do not feel we need to financially support someone else's online business by paying high/excessive fees for a connection we can not use. I will try to reach someone via telephone and certainly hope the response is better than the chat option. Good grief!
