Paytm Mobile Solutions — cashback not credited in my wallet

I ordered on 29 july 2018 order no is. CW[protected], but still not get cash back from paytm.plz credited my cashback in my paytm wallet as soon as possible. Maine abhi tak 20 mail kr chuka hu but aapke end se mujhe abhi tak koi bhi response nhi mila hai. Poor service quality.paytm ke traf se last reply 30 july ko mila ki 4 days mai credit ho jyga. But aaj 6 days ko chuke hai na hi cashback credit hua naa hi paytm se koi response aa rha hai. i think paytm coolwinks ke sath mil kr customer ke sath fraud kr rhe hai. Isse rokna hoga. Paytm ke against legal enquiry hona chahiye. Or ye farzi site coolwinks ko band krna chahiye.
