Uh.. the kind that is supported by 2 teams?

1st team Customer Service, who has experience in standard issues (pre-turbo) but limited support for turbo trial run.

2nd team Turbo upgrade running around checking and enabling higher speeds praying that nothing can go wrong.

I just wish that TM would’ve had a proper plan in the beginning - select less laymen and more supportive customers who can give good feedbacks and less complaints.

each telco has its own strength depending on ur location.
