They tend to be responsive when the installation request is made by fiber partners.

I spend almost 2 years making noise at TM about how my area is supposedly covered but when the contractor come, they can't find dp that cover my home.
They simply refuse to investigate it beyond counter database check.

Then I decided to turn to Celcom. They quickly pointed out how TM assigned my house on the wrong street and I just need extra poles.
Within 3 days TM contractor come survey pole installation and next month they come to install two poles (it was pkp time they have pole supply issue). Then I got my fiber internet.
