How to cancel Singtel by mail
Collect the details you need
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 Singtel is only as good as the details it quotes.
Put the request in writing
Postbye turns the request into a finished English letter headed “Subject: Cancellation Request – [your name]”: close the Singtel account, stop every charge and reply in writing.
Post the letter
Use certified mail for the 2113 Macquarie Park address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
It shows the date Singtel received your letter. Check your next statement: no Singtel charge should post after the cancellation date.
