Adelphia is slooooowwww with the internet service rollout. They sent us fliers saying it was available when digital cable was rolled out at my house in the country, I called trying to get it installed, and they told me it wasn't available. I called again, got someone else, they said to call back in a month. I called back in a month, they told me it wasnt available, and it wouldn't be available for at least a year. The fliers touting it's availability kept coming. I got sick of being jerked around and decided to stick with my modem internet service.
