Comcast Business "Service" sucks - 9 hour outage - 2 missed appointments and their response is simply, "I'm sorry". They promise 2 hrs appointment windows and 4 hour response time - when they can't meet it, they say, "we are doing our best". Asked for a manager and as soon as I said that I was recording the call, they said they did not consent to that and immediately hung up. Guess they know that they are not providing quality support. Guess their best REALLY sucks.
