ongoing billing for a closed account - 24 attempts to seek assistance, next step ACCC

[Annette1]

This is the most convoluted online support system.  I have had to cancel my card and reissue becuase of inability to get through to anyone at shopify to assist.  Emails are not answered.  Chatbot keeps ignoring request to speak to a human.  It keeps asking me to log into my shopify account which is closed and yet there are still emails coming through saying that have not been able to draw on my account.  The melbourne phone number now has an automated recording directing to customer support this is just going in circles.  Has anyone actually had any success with this company in relation to responding to a complaint
