Welcome to TPG Community!
We were able to locate your account using your community details and raised this with our Tech team to check your phone connection, but we were advised that they've contacted you and everything seems to work properly.
They did not hear any issues in the line while you are speaking with them and you've confirmed that everything is clear.
You may check your handset further or use a different handset for testing.
If you need further assistance, please let us know.
