Hi Nivlek,
I've wrote to TC as well on the common corridors obstructions. First reply, they will get officers to talk to our neighbour but see no results after 1month. Wrote second time to them, this time round they said they will talk to them again, send them warning letter and if the problem still persists they will confiscate the objects on the corridors. Two months have passed, nothing has changed!!! I'm not sure if TC is really doing their job?? maybe we should gather those who has the same problem and will go down to the TC personally
