I wonder how much this stems from improper mapping systems. They are always changing and potentially the price quoted was due to an incorrect map position given? This is a big reason why I don't trust quotes until I get some sort of confirmed pricing from the seller. Shouldn't have to, of course, but we kind of demand instant gratification and I feel this has led to poor service in many. I've often thought well Century Link handles cost predicting well but maybe that is more due to the quality of the service and the fact they are over-charging for a lower quality service so it's easier to guarantee those prices. That doesn't reflect in the price comparison but it does show when you have the service and your comparing to your neighbor whom has the other.
