Hey admin, My friend has an Samsung E7 smartphone. I downloaded PayTM and logged in with my account on his phone, but its more than 48hrs but haven't got any Push notification regarding Cashback code. I msgd PayTM regarding this issue but they said 'please send us a SS of your invoice'. Now the question is which invoice shall I send?? Does the product need to be purchased from paytm to avail the offer?? My friend had purchased the smartphone from one of our mutual friends shop. Help please!!!
