I am a mite confused.
internet & gateway (what are you talking about in regards to gateway?)
what type of speed is your internet? At what price? When you say gateway do you mean the Quantum Gateway Router? rental is $10 a month.
so now your price breakdown is $ 10 for the rental & $40.49 for your internet service if in NY it would be $48 and a bogus $2.49 Municipal Construction Surcharge
then you state you ordered TV local stations and Verizon charged you $4.99 extra and $12.99 for the tv box so $17.98 is $68.48 a month. You realize tv is taxed. So the bill goes up.
It is possible you have Verizon promotions which you lost or will lose if you try to revert back to just internet & router rental. That explains the discrepancy.
if not under contract just find a cheaper service. You can buy a antenna that gets local channels for around $20 on up. You save a ton of money.
