Indian Railway Catering & Tourism Corporation [IRCTC] — RAC tickets

This is from a really insignificant and a grumpy doctor making a complaint about the rac tickets... Whats the point of paying the entire amount and travelling in half a seat even for the first ac or second ac. And don't get me started on the response of the train ticket examiners... They are the worst.. I know they are under a lot of stress.. But they should provide information whether seat would be available or not. All i got is from grumpy stare or silence. All i am asking you is this.. Please don't put rac tickets for ac coaches and please refund the money if you cant provide a proper seat to the customers. Or else i am forced to see you as a money swindler and nothing more and i lost my complete faith in the railways and i swear i will never travel again if this continues to persist.
Yours truly,
A grumpy doctor
