One of best app available for smartphone for online transaction. I faced a lot of problem after old 500 and 1000 note ban. but now I can buy things without cash it is only due to paytm cash. I am using paytm since 1 year, early I use this app for recharge but now it helps me to buy things from market even if don’t have cash. customer service is also vey good. there is no delay in payment and the best part is that my account is secure and payment method is safe.
