They lost their card provider on Black Friday, same day as Jan3 and at least one other provider lost theirs – so it's likely that one provider cut several (probably all) of these types of services.

All existing cards have been canceled, and you cannot buy new cards. Unfortunately they have not been communicative about the situation, but I'd say they're unlikely to reestablish service any time soon, and any existing money you might have had with them should be considered lost.

That's always been a difficult service to offer. If they're shut down again, it would be the second time they've been shut down.

Update us if you find anything out

I think someone said it shut down the other day, no? You should do a search.
