So I have FIOS 100MBPs triple play and I just added Verizon Wireless unlimited for the first time. Now FIOS tells me that I have to upgrade to the Gigabit plan to get the deal. I thought Verizon had turned a corner on customer service but now I can see they are just as dishonest as ever and don't care about their customers. I've been a FIOS triple play customer for over 10 years. What a shame.
