Plan changing problems after ACP ended.

Recently after ACP effectively closed, I was faced with a billing dilemma. The Lifeline program was suggested as an easy fix to alleviate this problem, as an alternative of a small reduction in service charges, in previous emails I received, and I qualified, is actually a big confusion for most and not honored by Xfinity at all. I signed up for the plan in January, for a very good 2 year effective plan, prior to the news of the ACP termination. With a good price/speed ratio and was very happy with it. Now the price has jumped to $40 and as a low income senior citizen I can't afford it. Communication with Xfinity has gotten me nowhere. I can't change or select anything from my account that fits my needs. You are forced to have Essentials, which is not that favorable and still a bit pricey, or only upgrade to the more expensive plans. As an existing customer, there is no way to change or buy what they are offering to new customers right now, and there are a lot of really good plans out there. So should I cancel my Xfiniti account completely and buy a new one myself as a new customer or consider another provider? It's really annoying when I've been with Comcast for almost 25 years.
