Every month I get a different billing error with my account. It is just pathetic and a time waster. They bill me for services already included in my plans. I am over it.
I have had issues with mobile, NBN and now landline
What are the inclusions you are being billed for? What plan are you on?
How have you contacted Optus to raise this previously?
