I've called them before and $109 is a discount on the 1Gb. They don't offer everyone the same deal.
Wait.....You upgraded to 1G but you're only getting 300mbps? I think you should be the one calling them. Are you getting confused on amount of data vs. speed?
The guy came out and made sure we had a good connection. In fact, he told me i should call back and get the 300 mbps because in the wild west south of ankeny that is the best he has seen.
