Hi ATELG,
https://www.mauriceblackburn.com.au/contact/
Under phone fill - just use "04-yourSGnumber8digit" eg. 0496331234"
Under details fill - indicate your SG mobile number +65-96331234 and indicate you are 40F shareholders.
I submitted mine on 24 Dec and within an hour - a lady from Mauriceblackburn rang me back and asked a few questions including my loss value.
Are you in the SG telegram and whatsapp groupchat?
