Continually Lied to

I'm not even sure what to do or how to proceed.

Whenever I call or chat, I am lied to. I got an offer in November to lower my monthly bill. Was offered an option to lower it significantly but would be adding a mobile line. I was very unsure of doing this. I asked the employee multiple times what the catch was, if there was a contract, etc. I was reassured the multiple times that there was no catch and no contract. I knew I was going to be moving this month so I knew I didn't want to be in a contract because I was going to not need the services when I moved. Little did I know that was the first lie. Now come to moving month. Spent over 20 minutes on the phone with a gentleman to cancel my services. Again, I asked and tried to confirm everything multiple times (Internet and mobile cancelled, do I need to return the phone, return the modem. etc.). Once again I was completely reassured that everything was cancelled and nothing further was needed from me. Lie number 2. Now we're at today where I receive an email about my "new plan" with my "new charges". So I start a chat. 3 chats later I finally find someone useful. The name was Narender. They told me the line was still active and that I still had 16 more payments of $6.66. I'm furious. That's over $100 for something I never wanted in the first place and was not even told about. I'm sick of being lied to and taken advantage of to get money stolen from me. Narender was very helpful and understanding. They gave me a number for the "order verification team" to report the incident. However, the number they gave me is “no longer in service”. Once again, another lie and no help. Would love to actually talk to someone who knows what they’re doing and can stop just trying to take my money.
