I bought a new sim but after login to paytm, the name on profile was not mine, and then some told me that you have purchased a sim which was used and block by someone, so, sim company, introduce this number again. But when I done with my kyc, the name is now mine but the data is still old like cashback won, vouchers and all. Also, my mom is also using this, and whenever she does any payment, gets a cashback coupon but am not even I am new user to paytm.
