NBN constant dropouts

Level 2

TPG has sent out 2 different technicians to check the connection and claim the internet is stable now, when it clearly isn't from router logs and my usage. TPG now just straight up lying to TIO officer to get them off the case. TPG claims the connection is stable when they have clearlyed communicated to me in the past they can see the dropouts on their end.
Anyone have any idea what is causing this
