Major predatory sales tactic

In September, I was troubleshooting a tv issue with customer service over the chat option. As we were coming to a solution for the problem we were having, the representative suggested we switch from a landline to a mobile phone. He assured me several times that there would be no other changes to our account and that the monthly price wouldn’t change as well. 
we had a few issues in the beginning that were eventually resolved. 
fast forward to today, I attempted to use the home app to set my alarm and upon opening the app I saw an error message instructing me to call customer service to restore my service. After over an hour on the phone I learned that the representative that made the change to my account lied. Not only did he switch our phone from a land line to a mobile but he changed our entire plan. He removed a number of channels from our tv plan and removed our security plan. 
Since September, we haven’t had a security system in place and were unaware of it. 
Not only that but they refuse to restore my previous services because that was a “grandfathered in” bundle. 
The only option I was given was to pay more than $100 per month more for the same services we previously had.

No one I spoke to today could help me and finally informed me I would have to speak with someone in the customer solutions team tomorrrow. There is no direct line for them so they were supposed to send me a text message so that I could set up an appointment for a call tomorrow. I have yet to receive a text message. So I’m anticipating another long day of waiting on hold and hopefully being able to speak to someone from customer solutions. 
What happened to being a valued customer?

I can’t be the only one who has had this same issue.
