Address: CW 290 sanjay gandhi transport nagar Delhi 110042

Dear sir.
I work in CW 290 sanjay gandhi transport nagar Delhi 110042 . Sir, I usually use public toilet located beside my office but every time the incharge of toilet askes for money I try to make him understand that Delhi government had made it free but angrily he said I don't know Govt.
sir, The toilet is under MCD of Delhi but he has his own rules. It is the matter of corruption and must be solved as soon as possible.
