GoAir — change of 1 out of 2 passenger name (pnr - l3kwny)

Address:

N-8/180, B-51, Newada, Sunderpur, Varanasi

I booked air tickets of 16th september, 2020 from delhi to varanasi through sastiticket.com on 14th september, 2020 around 9:45 am pnr l3kwny.
First passenger name is mrs. Ritu garg which is alright but second passenger name is mr. Sharda prasad pathak which is mistakenly taken as mr. Ritu garg same as the first name. Kindly changer the second passenger name to mr. Sharda prasad pathak to avoid any further inconvenience.
