Paytm — refund of flight travel

Address:	201102
Website:	Paytm

I made a booking on paytm for chennai to delhi, travel date: 27th feb, 20 with airline air india. This ticket was made on 19th feb and due to some mistake in the booking, i placed the cancellation request within 4 hours post confirming with the airline of 100% refund.
Paytm took request over the call but cancelled it partially for 4 passengers, for rest 5 there was no request placed to airline. I called again on 20th feb for an update, paytm representative told 5 passengers ticket is still active, i asked them to place cancellation request again. For the cancelled 4 passengers, same day i got 100% refund and confirmation as well over the email. Paytm neither sent any confirmation mail of the cancellation nor placed request to airline. On placing several requests, paytm cancelled ticket on 26th feb and proceed refund of 360inr on 13k tickets by saying i placed cancellation request late. While i placed the request within the timeline of 100% refund, i again placed complaint on partial refund on 28th feb, for which there isno update till now. I sent all the proofs to the paytm, paytm repsentative are not replying over the emails, i have sent multiple remainders and call their helpdesk. It's almost 2+ weeks i"m calling them, they place new complain everytime but taking any action on it. Paytm is not helping in rasing grievance for this issue. Kindly help me in this.
