Fund freezes and cross-border transactions

Cross-border transactions conducted across borders have cross-border fees. Cross-border fees are chargeable currencies, including yen. For other currencies, a fee will be charged. I have had three withdrawals (remittances) from Kaiher global ltd so far. It was exactly the amount I requested from Martina manager. I have had 3 normal remittances so far, and I don't understand why the funds were frozen this time. Remittance name: Nishihara Yuuki, Moriya Yuuki (twice)
