I just tried to look up that service to understand it's options, how it might be administrated etc.
Went via a verizon page ( https://www.verizon.com/about/news/total-wireless-limited-time-switch-offer ) which recommended to get more info on a dedicated website https://www.totalwireless.com/ .
Unfortunately, that website only gives a box with an error message:

What happened?

Their webpage should be independent from their mobile data service, but who knows. Maybe they have a bigger problem atm?
Besides that, is there any administrative surface or other way where you could double-check that they registered the correct data volume for you?
