Yes because directly or indirectly you are paying for the memenship but don't buy from someone.
Mere sath bhi aisa huva ek ne mere ko SBI reward se generated Prime memenship de di....or na mere ko youths offer mila or na 500 wala......or mere 400 ki Jo membership Mujhe effectively mil.rahi thi... toda sa lalach ke chakar main 900 main padi..... customer support ne clearly mentioned kar diya ki aapne jab kuch pay nhi kiya to cashback kis bata ka....maine bola Paytm se ya other se to milta hai tab bola ki aap directly indirectly membership ke liye pay kar rahe ho..... so be careful.... otherwise L lag jayenge Bhai
