Ok, so yesterday (18th of oct 2017) i recharged my prepaid mobile with $20. My owing IOU came out leaving me with $17 and the charge of $2 for credit. (On the $2 day plan) my plan is still the same from 5 years ago, so that is unlimited txts/calls and unlimited internet. My plan hasnt switched over to the new one at all. Anyways, today is the 19th of oct 2017 and i checked my usage data after finding out i had no credit left and it said optus charged me $15 for one sms txt. I dont know how that can be since my sms, mms and calls are for free. Someone please help me as the live chat is too busy atm.
