Can any one tell me how to file a complaint to optus about their customer service. I need to write it in an email to be documented. Thank you
Write a letter (print out you email and send it via the post if you want).
They take that much more seriously.
Can you please share the optus complaints email id?
They don't have one @Dancan.
Either phone (its fairly hard to get to the complaint option), Visit a store in person or write.
IMO writing is the best way to ensure a response.
