Customer service - Glitches account right

Hi folks - I have tried contacting Myob account right team many times now . After waiting for 60-90 minutes, they transfer you to another department and then the phone just drop off. The chat system does not work at all.

To date we as a buisness have received the poor customer service - We have been with them since 2011. Seems like its time to change to a different software as we have lots of other things to worry about in busines. 

Does anyone know how to actually contact them locally in Australia? Do they have a comaplaints number?
