Misleading Bait & Switch - Followed by incorrect support - Followed by Legacy Plan Hijinx - VERY DISAPPOINTED 15+ year customer

I went on customer support to reactivate an email. Got sold on some new packages. I was told (and I have the transcript of the agent saying so) that I would get a speed increase, keep my same channels AND the 185+ package, and my bill would go down about $50 / month. It was confirmed with me 3 times that I would keep my same channels, as we explicitly discussed this as I was offered a lesser package first.

After moving forward with the new plan, I lost all of my premium channels, and DVR was drastically lowered. I also lost Netflix. Netflix I understand since we didn't discuss keeping that as it had slipped my mind. But the "same channels" was explicitly reviewed multiple times.

When my HBO no longer worked after this change, I contacted support again. They SEE that I have HBO and tried signal refreshes ,etc. After 5 days of this with different agents, all telling me yes I had HBO, but there was an issue with the box, they sent out a physical technician to my house. He got there, saw no issue with the box, and called his customer support contact. They told him I don't have HBO, or any of the other premium channels I used to have. 

The rep himself said "[Edit: Language]. They changed your plan and this was a legacy plan so they won't even change it back. I'd go to a branch and speak to a manager. I'm sorry".

After explaining this to a rep, the solution was to add back what I was missing... which makes my bill higher than it was before, AND still doesn't match 100% of the services I had.

Extremely disappointed. Very upset that this is how this went. Angry that as a 15+ year customer of Comcast, this is how they treat me when THEY are the ones that misled/lied to get a sale done. Won't be recommending Xfinity ever, if this isn't fixed, and will very likely just cancel the account shortly.

This seems to be a common occurrence around here based on some other posts, which is even sadder. Hoping a supervisor can get this corrected for me.
