Bruhat Bengaluru Mahanagara Palike [BBMP] — Garbage collection not happening correctly

Address:

23rd cross, old post office road, Doddenakundi, Bangalore, 560037

Hi
I am from Bangalore, Doddenakundi, Near Old Post office road.
I have started staying in this area since past 2 months.
I am seeing below issues:
1) the garbage collection can is not coming in a punctual manner.
2) they don't blow any whistle or make any sound, they come and don't know when they go in hurry.

This is bad, as a working professional we go to ofc in morning before 10, and by that time they don't come..and few times If I see them, I have observed that they don't notify people or blow whistle.

If they don't want to make sound that is also fine..but in that case they should come on time..so that we'll get an idea at what time they are coming.

Thai is going very worse, please help in solving the issue..bcz where we'll keep the waste if they behave like this?

Thanks
Simran.
