Indian Railway Catering & Tourism Corporation [IRCTC] — pantry food quality and very high price against normal price

I was traveling from mumbai to howrah by howrah mail superfast express (12809), i ordered regular veg meal for lunch but was shocked that i was charged rs90 but according to irctc food catering chart it's only cost rs50. Even after getting the meal curd and water bottle was missing and they didn't even provide. The quality of food was pathetic and tasteless. Standard of rice was very bad looks like 3rd class quality. Even though they provide two types vegetables but chappati were missing too. And after enquiring and showing the irctc menu they said we provide you two types of veggies and lit bit more rice so that adds upto 90 rupees. So plz looks into this case and act on pantry vendors.
