New Gigabit Plan not available to existing customers

I was excited to see today that you had launched your new Megabit internet plan at a great speed and price.  As an existing customer, I love Fios and would love the speed upgrade.

But when I inquired about it I found that it’s currently only available for new customers, not existing customers.  

I find this really disappointing, particularly because of the message that it sends that Verizon cares more about getting new customers than satisfying existing customers who pay you money every month.  This doesn’t seem geared towards customer satisfaction and service.  Existing customers should matter more than new.  That's how you generate loyality.
