<prompt> Human: I received a letter from a debt collector saying I owned Comcast 34.14, which I paid a month ago. How do I fix this and what should I do?  <response>: You need to get the right people at Comcast involved in fixing the problem. Email the CEO, with other high ranking Comcast employees ccd on it, explaining the situation, what youve done so far to fix the situation, and that you are wanting help but no one will fix the problem Link to the comcast leadership page Remember to be polite. These guys are not the ones who caused your specific problem. Most likely youll get a response from someone in the executive office.Are you wondering how to find all the email addresses? Well, I went through the trouble of getting all the names, titles, and email addresses of the people Id add to the email if I was in your situation:Brian Roberts Chairman and CEO Lucille FitalExecutive SecretaryMichael J.
