You could Google GfK and Verizon. It led me to something called the Verizon Foundation which displays a red box with the word Verizon and the check mark as display at the top of this page. Not sure what that is all about. Seems to me if the big dogs at Verizon Wireless were seeking customer input they would frequent this forum. Likely the only thing that would prompt positive changes would be a mass exodus of customers.
Me, I would toss the email.
