How do I see which card is being used to bill my account?
I chnged the card details but it is not clear whether it was processed since there was no acknowledgement and no follow up email.
If you've changed it successfully, then you may check the account if the new credit/debit card is in use.
Kindly login to TPG My account again and check the details.
You may also send us a PM with your TPG account details for further checking.
