Faced worst experience in Paytm wallet at HP Petrol pump. I had got alerted from paytm, there is upto 100% cashback offer at HP Petrol pump if we make payment via Paytm Wallet. So I have added 500 rupees to my Paytm Wallet and paid via Paytm Wallet at HP Petrol pump. But payment did not happen and application thrown error message. These guys are showing that they are promoting digital payment, but before doing all these things they have to deliver defect-less application.
