If you've never logged into the new My account before, please see TPG Mobile - Introduction to the new My Account - TPG Community
Note: If you have an outstanding balance on your account (e.g. an overdue invoice), an automatic payment for the amount owing will be attempted when you save your new payment details.
Step 1 Log in to My Account and select Payment Details.
Step 2 Under "Payment Method", current payment details will be shown. Select Edit Payment Method.
Step 3 Select either Credit Card or Direct Debit, then fill out the required details for your selected payment method:
Step 4 Click Add Card or Submit to submit your change request and finish.
Please note - this online update does not work for me - the "edit payment details" button is greyed (pinked) out ... I have an error message at the top of the screen telling me "An existing payment transaction is in progress" ... but I've waited half a day and the message still has not gone away ... (refer attached screenshot) - I did phone for help as well, but the wait time is presently one hour.
It does not show the 'edit payment method' box.
I just waited an hour on the phone to pay my bill and was then told to call back in office hours. Not very helpful.
Since you have started to change over my accounts, the payment details are being changed over incorrectly.
You have already cancelled my first account, and now I'm afraid you'll cancel my others. Please transfer my payment details over to the new account. They have not changed.
I look forward to your reply.
