I owned a unit nearby amara..we dont even have unifi after years. The problem comes from tm and also developer.
Tm wil only lay cables when they have at least 50% demand.

Have u try staying in BU 11? Not sure abt now but 3 years back i am stuck with maxis for 8 years before I rent my unit out.

And now I am staying in BU 6 , applying thru kedai Telekom is hell , they can tell you in the system u cant have unifi but when u told them your neighbours has unifi, they will request you to give them your neighbours telephone number to check.

My suggestion is write or email to the management instead of ranting here. Problems won't go away or solved by itself .
