Internet bill change

Why would you take a current customer and hike their bill (already 25% higher than the current 5-year promotion) over 25% and then not allow them to take advantage of current offers? You have a 5-year plan for $60/mo for anyone signing up as a new customer, yet an existing customer you want to charge $110? Literally a marketing plan created by the mentally challenged. "We don't care about our loyal customers". It's a finger in air at we loyal customers. I will be changing to AT&T for half of what you want to charge.
