Gsrtc — parking fee receipt

Address:	GSRTC, Gitamandir bus stop, 380022
Website:	gsrtc.in/site

I used to park my two wheeler at geetamandir bus port of ahmadabad city. There it is privatized to better management. The system is good but the concern and the problem is that this people are not providing any receipt of the parking fees.
Whenever i asked them about fees receipt they denied. Same was mailed to authorities but no reply from them as well.
