Worked for Comcast as a Business Account Executive (Salesman) for 6 months. Great product but the worst customer service imaginable. I walked away after a Comcast install went horribly wrong and left a customer with 15 phone lines without service for 3 days. I just couldn’t work for a company where customers call you in tears because your company has cost them 10’s of thousands of dollars....
I used to work for Comcast Business class and Residential. Small world... I was a support tech though before they outsourced everything to 3rd party contractors.
Phone installs are always tricky because if the install is cancelled improperly the lines will snap back to the original provider and then you’re at their mercy. Working phone LNP was ridiculous with all of the porting rules we worked around.
