Did you know that Comcast has an “on-time guarantee?” That’s right, if your tech arrives outside the time window for a repair, you’re entitled to a $20 credit. For installs, you get one free cable outlet installed. A former Comcast worker says, “Only dispatchers have the ability to put this credit on accounts, however,” which makes us wonder how easy it is to actually get these applied to your account. Maybe if you use these numbers to call dispatchers directly you’ll get somewhere. [Comcast]
