Can't register for the visa prepaid gift card

I signed up for the Verizon gigabit service and as a promotion offer I was eligible for $200 gift card. I have tried multiple times registering for that but getting the error every time (Our apologies. Due to a system issue, your registration was not successful. Please try again later). Customer service is not much of a help and online chat wont handle this issue. How to register for the gift card?
