Verizon review: fios internet fios tv billing & discounts

Received flyer in mail in MAY advertising Verizon/FIOS TV, Internet, Phone with $500 debit card (yes, $500!). Called to ask what TV channels were included; signed up with phone service rep who VERIFIED THE $500 OFFER. Installer was on time & helpful, but didn't provide much instruction in using unique FIOS features (or even email). SMALL problems on every single bill received to date -- discrepancies in charges, no credit for first movie offered "free"; that sort of thing. Phone billing dept. DID re, , solve promptty & courteously, but problems shouldn't happen THAT often! Also serious and ongoing problems using On Demand -- it is impossible to read if you don't have giant-screen TV and takes FOREVER to navigate. I STILL can't find movies except by pure chance. Debit card DID NOT ARRIVE in promised time frame. Called; clerk in "Rewards" dept said it hadn't been "cut" properly and they'd have to "cut" another one (WHY NOT DONE AUTOMATICALLY - OR WHY NOT NOTIFY ME?) The Rewards Dept. clerk VERIFIED the $500 amount AGAIN. That's one flyer, THREE PERSONNEL all said $500. Debit card FINALLY arrived midway thru 5th month of membership. FOR $400. Called; first told agent i'd talked to didn't exist, then that he DID exist but wasn't there. Called next day. AGAIN told he didn't work in that dept, and then told yes, he did work there, but again absent. THREE MORE AGENTS said there had NEVER been a $509 offer, even though I'd HAD IT IN MY HAND (flyer) and VERIFIED IT with THREE different agents. I DON'T LIKE COMPANIES THAT LIE TO CUSTOMERS. The MINUTE my 2 year commitment w/Verizon is over and they can't charge me for the debit card bonus, I WILL BE GONE. CRAPPY COMPANY - GO ELSEWHERE IF YOU CAN!
