MYOB Business file READ ONLY and unable to use, need urgent help

My client's file has now been 48 hours in READ ONLY and MYOB seem to be unable to help.

Client and I have spent hours on the phone. Can't invoice, can't run payroll and can't pay super which need to be done THIS WEEK. Can anyone help? So frustrated with MYOB. We know it is a glitch in the backend of the file and appears the file is now owned by MYOB not my client.
