Coolwinks — money back not received

Address:

Gurgaon, Haryana, 151509

During coolwinks 100%moneyback offer I purchased a eyeglasses worth 1904 as acc. To t/c I will get 1904 cash back after 14 days of delivery but after 14 days I have not received my cash back . I have done payment through my Airtel app plzz help me with my issue and help me to get my money back. Also when I tried to call them they are saying see T/C and you can't club this with any offer but I have not used any offer . Also I have confirmed my cash back from them after 2 days of delivery they said u will get cash back after 14 days but they r just making fraud now
