How to cancel Iinet by mail
Gather your account details
Put the account number, the phone number or service address being cancelled and the name on the account in front of you before you write: the request to Iinet is only as good as the details it quotes.
Draft the request
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the Iinet account, stop every charge and reply in writing.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 6000 Perth. Keep the tracking number it gives you.
Save the tracking record
It shows the date Iinet received your letter. Check your next statement: no Iinet charge should post after the cancellation date.
