From my experience ...
MBPJ will send u all the warning letters but they wont send a court letter..
DBKL they wont even bother about you they wont send any letters..
MPSJ i dunno...
MPS (selayang).. they will send some letters.. but not sure about court and all...
Too Many DBKL, MBPJ, MBSJ Summon, will it bring any treat ?
