Back on internet

Finally I'm online after 1 week of no connection. This morning SN tech support guy came again and as what I suspected he didn't see problem that I was facing previously. He did the line test, connection test and bla-bla testings all seems to work 'perfectly' fine. How unexplainable can this be as I'm seeing problem over 2 months. Anyway this is not his fault, he just a poor technician go round island listening to SN customer complains about how bad ISP service is. From now on, I definitely not going to sign up with this ISP when my contract end.
