I have asked for our Mobile team to assist, if you can private message me with some verification details
TPG Account Number
Telephone number attached to your account.
That will help us help you.
I believe this is a Singapore number.
TPG Australia & TPG Singapore are 2 separate companies. Kindly send an email to Singapore Mobile Team at email@example.com so they can provide further assistance.
