For few months my Optus bill has been very high,sometimes $200 i recently checked it was from some type of games which i never subscribed or played. Would i be able to get refund from Optus?
Should be fairly straight forward.
You should have recieved some SMS related to the scams? (Send back STOP to the number)
Contact Optus. Ask the to set your PREMIUM SMS LIMIT to $0 (This will stop it happening in the future)
Request Optus refute the charges for you (This can take one or two tries as some Optus staff will say we can't do that, others will say Sure, No problem)
It may take a week or so for the process to complete but the fees should be refunded to your next bill.
