Who I have the same questioned this topic

HLPE!  Each time I need to upgrade my phone paid Verizon Associates have quoted me a rate which they changed during the purchase process.  What kind of shady business doesn't honor what they say?  I have wasted hours trying to ask for Supervisors who don't call back.  Is this a publicly traded company?  How can I escalate my concerns?  How can we inform all of the shareholders what is really going on?
