Delhi Transport Corporation [DTC] — low frequency of 615 bus service in evening

Dear sir
I am a day scholar jnu student, who come to jnu every day. It is really not possible for me to use auto everyday so i use 615 bus. But 615 bus frequency is very low especially in evening. Maximum time i wait for bus was 2 hour then i have no choice to take auto and it happen every evening.
So really desperately request you to provide regular bus (615) service from jnu at least for gap of 30 minutes. I really don't have income of my own to pay auto everyday day.
Thanks you for your time and consideration.
