I am currently travelling overseas, didn't check SMS regularly. I just found out my telstra prepaid number was no longer active since last 22 Nov.
I have tried to recharge it but failed.
I called customer service team and online chat with customer service team as well, got feedback is I can't take my old number back.
Called Telstra prepaid team again to confirm, representitive talked to me that it is still a on-going process, I can switch prepaid to post paid if the de-activate process finishes and I can still use my old number.
The old number is very important to me, all my bank info, credit card, insurance and etc are associated with it. I can't change my number.
