Welcome to TPG Community,
You can private message to me your customer ID, username, old service address, new service address and mobile number, planned moving date so i can check here.
I am able to see that now service is active for new address. you can't have active service two place. If you want to active service at old address it will normally take some time because TPG need to contact Nbn for that and during this pandemic nbn team is taking longer than usual time to activate service. After that you need to wait again to activate service at new address again so its upto you. This is matter of 4-5 days so it would be great you arrange alternate option.
