Paytm — Cashback not received from paytm

Address:	Gautam Buddh Nagar, Uttar Pradesh, 201301
Website:	paytm.com

Hello,
i am bharat singla. i am booking three flight tickets through yatra.com. and i pay for these flights through paytm. As per yatra.com and paytm offer. they give 300 rs cashback in paytm wallet if any one pay online to yatra.com from paytm. i book three flight ticket separately one by one. and pay separate for each ticket. as per offer. now i am eligible for 300 rs cashback of each ticket means 900 rs as cashback. but i receive only 600 rs cashback. i call to yarta.com and they ask me that they already send my cashback to paytm so it is the paytm fault. i try to call paytm contact no. no one pick up my call. and they charge 50+ rs for call. i write to paytm in complaint about my problem. but no reply. now i am fully frustrated from paytm. so i file my complaint here in consumersompaint.com. i hope that now my problem will getting solve. i want to ask people do not use paytm. it is worst site. and i also want to give suggestion to paytm. please improve your customer helpline and provide any toll free no. so people can easily call.
Thank You!!
