Municipal Corporation Of Delhi — Garbage Collection Vans missing

Sir,
I am a resident of F-94, Bali Nagar, Delhi - 15 and we are facing a problem due to garbage collection van which doesn't come regularly. If it comes also then it doesn't stop at all. Due to which lot of garbage gets collected and starts stinking. As if they have done some sort of collaboration with private street garbage collection people.

We have a option to switch to private street garbage collector but, why?.
This is the facility started by the govt and they are being paid off for doing this duty not for sitting at home.
So, please look into this matter.
Regards
R/o F94
