ADSL dropping connection

Palpatel
Level 2
I am using ADSL2 from over 5 years but last weeks too much connection problems. I restart modem many times but it work 5 minutes and dropping connection. Even can’t watch 5 YouTube video easily.
This time very hard to contact tpg. Last week I spend 1 hr to chat tpg help but guy didn’t fix the issue and told me that ,sorry I am not trained for ADSL.
Where I need to talk now. Wasting time and money.
