I was informed by staff of Optus when we called about the bad internet line and was told thate they will not charge us for almost two months of bad internet connection but I still am being billed monthly for the same charge. Please advise.
You will still see a bill for your monthly figure as that is what you agreed too, what will happen is a credit will appear on your account. If the credit has not appeared, consult with billing via 133 937 or live chat to discuss why it has not landed on your account yet.
They can but how would they safely identify your account online? Also it’s not designed as a way to avoid using the regular channels though. You’ll find if you chat or call you’ll get a quicker response.
