Thank you for your recommendation, Amanda, as I am trying to cancel my MYOB subscription, too. Unfortunately, though I have tried several times to cancel my subscription via the number you have provided, I have been advised each time that they are unable to take my call due to a high volume of calls.
I have informed my bank to stop payment on the subscription and I have tried several times to inform MYOB. This is extremely difficult when I can't even speak to anyone on the number provided.
I have been purchasing and using MYOB products for over 25 years in the small business and not for profit sector. I hope that you can help me to cancel my subscription in a dignified and professional manner.
