Jet Airways — ticket date reschedule

Address:

605009

Dear sir/mam

I have booked ticket from delhi to chennai. I mistakenly selected date as 15 apr 2019 instead of 15 mar 2019. I need to reschedule the date. Have to know about charges involved in changing the date. Trying to contact toll free but more than one and half hours my call on hold. They didn't connect. We booked using paytm app.
