Telangana State Road Transport Corporation [TSRTC] — not giving water bottles in buses

Address:

Hyderabad, Andhra Pradesh

I travel in rajdhani ac bus from hanmakonda to hyderabad on weekends since two weeks they (Helpers and drivers) are not providing water bottles, though they are taking 15rs for the same. They do take 15 rs from every passenger. It's clearly mentioned in the payment details that 15 rs goes for amenities.
This is not only restricted to hanmakonda and hyderabad route but also to other cities
Please look into this problem and take action
