Konkan Railway — about food facility which we have taken with the e - ticket

My mother mrs sumati sukale and mother in law mrs suvarnlata thakur were traveling on tejas express (Train no : 22119) from thane to kudal on 24apr-2018 : ticket details as follows
Pnr no : [protected], seat nos : c6/1/ws, c6/2/nc. They had paid for food facility, but not served the same till kudal station arrived inspite of asking 2 to 3 times to the catering service person on train. Is this the kind of bad services indian konkan railway provide to their passengers. I want my food charges back and what preventive action will be taken, to avoid this kind of in-hospitality in future.
