Welcome to TPG Community!
We were able to locate your account using your community details and learned that the case was already being handled by our Engineering team.
They were able to talk to you yesterday to inform that all of the override calls are working on the network. They've advised you to retest and to contact them with the result.
The ticket is still open and within their monitoring. Please contact them once you have the result of the test.
I understand that our Engineering team has been in touch and the case is now raised with our Network Engineers for further investigation.
Updates will be given by your assigned Engineer once available.
Should you require further assistance, please let us know.
