Employee disconnecting my service intentionally every minute using their credentials and hacking into my account..

I have tried contacting chat who told me there is nothing that can be done and did not offer a solution or initiate an investigation. Matter of fact, each time I contacted chat they made my internet diminish even more to the point that made it seem like a modem issue, to protect the employee when the modem was perfectly fine. Yesterday, when I chatted for 4 hours about the disappearing wifi names on the devices and in my customer account, they used the previous chat conversations to incompacitate the modem to where now it no longer works and the agent i was chatting with took it upon himself to already have a technician appointment scheduled for a certain day. The scheduled appointment just popped up in the chat. I said who scheduled this. No asking me is this date and time good for me or would you even like to schedule an appointment. He forced that appointment on me. Xfinity employees should not be able to use their credentials to access customer's accounts and mess with their service, harassing people. I'm disabled and they think I'm easy prey. Think again. I want a corporate investigation into all employees who have accessed my account and who have left footprints of pushing the disconnect button every minute for the last several weeks. They make my wifi name disappear from all my devices as well. They started doing this about once a week six months ago. Now they are disconnecting my internet and removing my wifi name and password too every minute. I want an investigation and punishment. My disability association is not pleased. Employees should be ashamed covering hate for each other as well through the workplace. I wish I could attach the chat conversation over the last months since it's one long thread. But it is toooo long. And they made it so my devices can't download the app on a phone I got recently from xfinity nor update on another phone. Deleted the app, cookies and cache, the app won't install, still.
