Review Public Liability Cover

Please explain why would Outsurance deduct a premium for the month of April when we were on lockdown level 5? It's a known fact that all of us who do not provide essential services were home as per instruction from the president. My Company, Amazizi Projects and Events Pty Ltd pays Outsurance for a service provided. So if you could please, ease enlighten me what service did you provide for us for the month of April since we were all locked down? What cover did you provide for last month and for what?
