It's odd. Perhaps fraudulent scam. Leopay has detached its business from Satabank and now relies entirely on iCard AD. Do you still have a Maltese IBAN with Leopay? They migrated to Bulgarian IBAN this summer. The e-money accounts are not backed by government compensation scheme but your account should not even be linked to Satabank at this point. The proof of this is your Bulgarian IBAN.
Satabank did the euro currency clearing & settlement for the Bulgarian owners group of companies (i.e leopay etc). That was the whole point of why he established the bank in Malta in the first place - to get direct TARGET2 clearing of euro payments for the group of companies he operates. Leopay owner had already started the process of de-risking from Satabank late 2017 and had moved most funds I guess before April 2018 (possibly to unicredit bank ) . They also switched from MT Ibans to BG Ibans in April if I remember as leopay moved under i-card in Bulgaria. Once Satabank was suspended in late October it hit leopay, icard etc as they were using Satabank for euro payment and settlement purposes. However those leopay payments that were inflight via Satabank's euro payment services got stuck and now those clients are.....not happy.
Anyway good luck.
