Welcome to the community!
I am sorry to know that you're having difficulty with your service. I was able to locate your account using your community details and seen that your connection has been raised to our Engineering Team currently under assessment. We will chase this up with them and request a callback today for the case progress.
Our Engineering Team raised this to Telstra and have told us they have booked a technician to check your TPG service anytime between now and 23/Nov/2018. Let me know if you would still like to speak with one of our Engineers for the case progress.
