Customer Service chatting with an agent

Every time I even think of Xfinity, I think it take years off my life and I’m not being negative. I get so stressed out every time I chat with an agent I never get what I wanted and yet it ends up, causing me more money every time so then I just talk to somebody higher up and get a massive attitude. I won’t say his name but I’m really thinking about going to Verizon. I can’t take this anymore
