I am having trouble understanding how my bill has increased tp this level when prior to September 2019nI was paying about $42.00 a month. When I checked the bill, it seems my plan has been changed to the current and a phone has been added. I had no intention to gain another phone as one is adequate for my purposes, and the plan I was on was adequate for my lifestyle.
I did attend an Optus store to inquire about getting another phone but was told due to my credit history that was not possible. It has happened, however, and this makes me think my account has been hacked.
I have taken so long to inquire to sort this out as I have been investigating this for my own personal understanding.
I am unable to pay the requested amount except if its restored to the original plan.
Sound advice from Peter in his response. I would just add that you contact Optus directly in writing. Either by sending a message or if you have a social media account, please send a PM to Optus on Facebook or a DM on Twitter with the details.
