Tambaram Municipality — Im complaining about garbage pickers in our area

Dear sir/madam
We are living at 2nd street kutinji nagar west tambaram.. Garbage pickers in our area attitude is very worst here. They are demanding money regularly if we are not giving they are not picking garbages. If we give 20 rs they are insulting in front of others. Is there any rule we need to give more than 50rs? I hope there is no rule to give money for them but still our street people often we give money. If someone pay low they shout and insulting in front of others. Please kindly take action against them.
