Similar situation. spent an hour with customer service on the phone and they told me to call #PMT. Now on chat tech again (2nd/3rd time)... Verizon system seems tricky... this shouldn't be hard to take care of. it's just 500MB of additional data, but that data is important!

under My Usage (Balance Details) it should label the 500MB as bonus additional data.. doesn't show it anywhere.. ::frustrated::
