Hi @bishesh,
Welcome to the Community!
For customers experiencing any issues with their service, we recommend the best thing to do first is check if there's an outage.
Check our Service Status page for any known outages.
If you're on NBN, we have created this article that can guide you on How to Check for NBN Network Outage
I would recommend to also check the status of your account by logging on to My Account
Should you need further assistance, feel free to search community for help or chat with us at https://www.tpg.com.au/support/contact/ and we'd be glad to assist you.
Regards,
