Bruhat Bengaluru Mahanagara Palike [BBMP] — Garbage collection not collecting properly

I am staying at btm layout 2 nd stage, 16 th main, 12 th a cross, opposite micolayout police station.Here vehicle is coming for garbage collection.There is no particular time for them.once they come at 8 morning or 9 or 10.we stay in a building 3 rd floor.we won't come to know when they are coming to dispatch garbage.I am going to work daily so that I cannot keep waiting for the vehicle for dispatching the garbage...we have to give garbage in their hand..if we keep it down infront of the building they won't get down and collect...we have to wait for them then we have to go and handover...it is very difficult to office going people..for flats they will go inside and collect the garbage...for individual building they are not doing...I kindly request you to solve our problem..Please let them get down from vehicle and collect the garbage which is kept infront of the building...
