Need an internet plan

I don't want to leave Xfinity but every time I call all they can offer me is the same price at $65 a month and cut the speed in half..I have been with Xfinity since the were Verto Cable! 40 years! I also have been with mobil since they provided it! They are telling me they can't offer me anything..I moved last October and was never informed about Xfinity Now or anything that could save money and I asked! I'm disabled and on a fixed income.. they shut my phone off and turned it back on three times. They changed my phone number without my authorization once. Thank God I caught it. It took me 2 months to get my phone working. I think I talked to about 150 customer service representatives and finally had to go to corporate. I was treated with disrespect lied to and my phone still isn't right I don't receive voicemail notifications. And this is how I'm treated after being a loyal customer for 40 years!
