Sorry mate, didn't see the reply. They have regular work hours (I can't remember the exact hours of operation but we can use 9am-4pm Eastern as a decent baseline). if you request someone during regular work hours and nobody picks up (there are various reasons why something might have happened), just retry - no harm done.
As Blueberry pointed out, it's possible these pre-paid cards add a specific balance to your store wallet, not the in-game menu (these types of cards are sort of uncommon, so apologies I didn't pick up on that right away); this is a way of circumventing the minimum deposit rules which can be super beneficial for games with cheap MTX. You said it shows the transaction going through which is perfect so I'm sure one of the agents, whether it be EA or sony/microsoft, will be able to sort it out.
