Same experience here with fiber and telecom services. They quote crazy prices for services I already have from their competitors at the lower published rates.

These potential vendors have zero or near zero additional cost to activate service (eg: the OptiTap is only a few tens of feet from where an ONT would be install), yet the sales reps call me every few months asking when I want to light up service and aren't ready to even talk price or SLA, despite knowing what we pay their competitor.
