The FCC is always the answer
Two years in a row I tried to take advantage of "loyalty customer" offers sent to me by Verizon Fios, for a Verizon Wireless "Free phone". Both years the original offer wasn't what they claimed it be and I spent 4 mos the first time getting my money and reurn8ng their equipment and this year, I just so happened to screenshot the deal, si it only took 2 months to get offered a refund. But only with a FCC complaint.
NOTHING ELSE WORKS.
