Welcome to TPG Community!
We’d like to get to the bottom of this and want to get this resolved for you. Ive searched for your account using your Community details and was able to find a match.
I've ran a remote line test and this shows no physical issue on the line.
But I do still recommend that we have one of our technicians give you a call to resolve your issue as your service may be affected by other factors.
Please let us know your best time and contact number vi PM so I can get a technician to call you.
