Yeah their billing is terrible but often times if you are polite you can use it to your advantage and get free trials movie packages, etc. But definitely, the billing does bring Fios down a notch. Personally, I'll take billing issues over caps any day, as billing issues can *usually* be fixed/credited...

I tried for about 6 months to get the billing fixed. They are so compartmentalized they couldn't get it fixed. I even went as far as canceling ALL VZ services and having them reinstalled only to have the same billing error reappear. Service itself was excellent so I still would HIGHLY recommend it on the condition that the person do everything "by the book" and be patient with canceling previous services and the like.
