Well, finally had my first real Safe snafu. I loaded two packs yesterday and then went to load $1K to T-Mobile. I got a success message and thought nothing more of it. When I checked T-Mobile several hours later, it only showed $500; Safe shows $0. I can see in my history the two $500 loads, but transaction history shows only $500 moved to T-Mobile.

I called RL and they at least seem to acknowledge the problem (though can't explain how it happened). They have opened a problem ticket for the missing $500 pack.
