Still waiting for assistance

I've been a customer for over 20 years. The service has always been spotty, but at this time there is no other option. We pay around $125 a month for internet service only. We were given a "completely free, no charges ever" flex box which is basically like a rough. Our internet often goes off or will be going slow and we'll realize we're not even on our own wifi but on a neighbor's (why is their signal stronger than ours which is a few feet from where we are at anyway?). Main issue, the customer service offered on the official app is beyond a joke, a very frustrating joke. The reps are aggressive and push you to quickly view x, y, z and accept for this "lightening offer" (no joke, this was a part of a conversation with a rep when all I was attempting to do was cancel Disney). I don't want a phone line, or a new phone, a new iPad etc. I want any and all add on subs which I have not ordered and have not been used, to be cancelled, for them to stay vancelled and I want a refund for approx a year, maybe more, of a sub to amc which we never ordered and it was never streamed. A rep said they could refund Dec and Jan but not the rest. That's pretty unacceptable and would like a refund for all the months billed. Also the lowest price they could offer was just under $100.... for spotty I telnet service to a customer of over 20 years. New customers can get the same service for $50 to $60 a month, locked in  years. Why can that offer not be applied to long haul customers? If it wasn't for the fact I need the internet gpfor my son's homeschooling I would just get rid of it. It's become too much of a hassle and not worth it at all. I doubt I will be offered the half price for 5 years plan new customers are being given, but I do request/demand a refund for all months of AMC ( snd any other add on service which has not been used and I know there's a way to check). Full refund and an invoice showing the refund(s).

Thank you, I do hope to hear from am actual rep or manager soon.
