I need to cancel my post-paid SIM only OPTUS plan, ASAP. I had to rush back to my home country due to Coronavirus, and did not get a chance to cancel my plan while in Australia.
I tried calling the number that the website gave for international callers, however my phone will not connect to complete the call. I am unable to call to cancel my plan and therefore need to do it online. How do I go about doing this?
