Indian Railway Catering & Tourism Corporation [IRCTC] — extra charges, bad service and behavior of staff

I was traveling from mumbai to indore through avantika sf express (Train no.12961) in 3rd ac (Coach - b3-5) on 26th february 2017.
As per my expectations 3rd ac service of such a long route journey train should be very comfortable. But the journey was exactly opposite to my expectations.
The staff was very rude and does not provide all the services as per the guidelines.
Also the dinner was charged extra. As per the charges mentioned in ticket the veg meal should cost rs.50 but they charged 180 for single plate dinner.
And when i asked for the bill of that dinner, the attendent said no to the bill and said "khana ho to khaao varna rehne do"
Next morning when i asked him to give me a napkin which is included in bedding, he denid to give me the napkin and said to manage it by myself. Such behavior and extra unnecessary charges was not expected from a super fast express train attendent.
Will not travel in this train again. Very bad experience.
