Hi @viraj_g ,
Welcome to the community!
Thanks for raising this to us. If you wish to make a payment and re-active the account we did an article that you may find helpful, this will guide you on how to make a payment online. Please see the link below.
If you still wish to speak with one of our Account Specialists, feel free to shoot me a private message with your account details (Username/Customer ID) together with your best contact number and preferred time.
I recently attempted to perform an outgoing call from my phone, but when I tried to, it did not call, rather, I received a message from TPG that my account is expired and I need to contact TPG Customer Support. I'm not sure exactly why this has happened. What can I do about this?
