Xfinity agent lied to me

I regret getting xfinity services. It is near impossible to talk to someone and I have been disconnected from the chat or promised phone calls I never received. I was Initially lied to by an agent who told me it would cost me nothing to add a phone to my line. I paid $55/month for my internet and the agent said it would only cost me $55 a month for both my internet and phone service. He said I wouldn’t have to pay the $45/month for my phone for 2 years. I clarified with him multiple times. Even got an email stating what my bill would be. “55/month for new and existing services”. I tried to contact agents with no avail. Told I would be called but no call received. Do not get xfinity.
