I am earning Verizon Dollars by using my Synchrony Verizon VISA card. I no longer see an option to use those Verizon Dollars to offset my bill payment, (or do anything else with them, for that matter).
I've got a helpful FAQ here that outlines how to use earned VZ Dollars to help pay the bill. It is in the section 'Earning & using Verizon Dollars.' Question #7: https://www.verizon.com/support/verizon-visa-card-faqs/
Additional information on Verizon Dollars can be found there as well.
