I am hoping a moderator can respond to this message because I have had no luck getting this sorted with your customer service over the phone.
My previous plan had expired on 29 March 2018 and I purchased OppoA73 on 28 April 2018 to update my plan to the $40 - 15 GB online special plan. I received my new phone on 2 May 2018 without a sim card so I went into a physical Optus store to get it sorted out. After calling your customer service 3 times my new sim was activated and I was reassured that the new plan was processed. I have since gone into my account and realised that for some reason my original order was cancelled and instead of the adding the $40 - 15 GB plan that was adverstised and I signed up for, Optus customer service has added a $40 - 500MB data plan to my account. I have called optus customer service and they have told me that they would sort it out but nothing has been done. I am really confused why it has been so difficult to process my order per what I actually ordered. Can someone from Optus team please respond and help me out because if it is not resolved promplty I will have no choice but to make a formal complaint to ACCC and Telecommunication Ombudsman.
