My experience with this app was so bad I had buy 2 sunglass with total amount 1500rs at an offer of 100% . cashback but they dont give any cashback on my order and then I want to cancel it but at return they takes. my 150rs as a penalty of my cancellation order this is not fare . due to this reason I cancel my order and then I call them but they dont give any responce because coolwinks not have any 24x7 helpcenter for consumer care I got suprised by hearing this type of response from one of Indias highly reputed optical company so I request you. to that was a waste thought to spend money on coolwinks thankyou
