I was curious if I could technically overpay a few months of my bill on purpose and have it credited toward future bills. I was wanting to pay like 10 months of the bill up front if that's possible, but there's no legit way to do that on the site that I can tell.
update: I talked with a verizon representative, and it looks like this is possible
You can go into a physical Verizon Fios store and use either the kiosk or have the counter person apply your advance payment amount to your account.
save the receipt in case you run into the old “we have not received your payment” crap.
