Nandini — refund and compensation of flights cancelled by jet airways

Address:

f346 okhla industrial area, phase 2, New Delhi, Delhi, 110020

I bought a jet airways ticket (Pnr no. Twplcx) delhi-dubai-delhi ticket 12th to 15th march'19. Both flights (9w508 & 9w507 have been cancelled by jet airways. I now have to buy new tickets at a much higher cost. Also, i would like my refund according to ddca rules.
I have been trying to call their phones since the last two days but they seem to have blocked all phone lines.
Please help me get a refund & compensation i cannot take this strain as i'm a senior citizen..
