Xfinity Customer Service Lied to me

Throughout the past couple weeks Xfinity has made things extremely difficult for me. I originally had a two year contract which went smoothly. However, after that expired my bill went from $75 a month to $180. This was an absurd price increase so I immediately went to talk with an agent. I talked to a couple of agents eventually I was told I would receive a refund for the previous months and have the price reduced to around $80. This never happened. This process took up an absurd amount of time and by the 10th agent I was able to find a new deal. I made it clear to the agent I would be canceling the service when I moved out two months from then and because of that didn’t want to be locked into a contract. The agent informed me that I would not be getting into a contract. I even paid for the more expensive bill because of this. I then went to cancel the service two months later and lo and behold I was in a contract. The problem was I ended up signing it trusting the agent was telling the truth. Now Xfinity refuses to refund me. After talking to over 15 agents through this process I have realized every agent tells me something different and I know a lot of people who have had similar situations. It really baffles me that a company this large is able to get away with this. The craziest part is Xfinity has the chats saved where an agent lied to me saying I wasn’t going to be in a contract. Even with this, they still refuse to refund it. If I were you I would stay as far away from Xfinity as possible. Their customer service is one of the worst things I have ever experienced and nobody knows what they are talking about. Not sure how they get away with this.
