seems that no one can help.
Since I have waited for nearly a week but no help or reply from tpg both online and call back, I have to report it to TIO.
sorry for the pain but this is the only way to resolve the problem.

get a few calls from TPG. what they ask me to do is just speed test and test. boring
yesterday they sent me an email that asking me to do some tests coz they dont have any technicians available here. Fine. I followed their instructions, took me 60 mins to finish everything and uploaded all results. u think it is over? I got an email from tpg this morning 'thanks for ur reply, now we request u to do the test again.'
TIO said they will step in if they dont fix the issue until 25 August. I will see what happen next.
