Marina Sometimes payments couldn't be sent as Instant Payments. Those payments are then sent as regular SEPA transfers, which take 1-2 business days. I'm not sure if that's the case here, hard to say.
I think the only thing you can do is wait for 2 business days, and then contact bunq support again or Paysafecash support to ask if they can help you.
Unfortunately, depositing cash money with Paysafecash isn't always working correctly (according to the posts I see here on Together), so try to avoid it if you can.
