Present days all online transactions done through apps only. Paytm is the most useful app for all recharges like mobile dth power bills train, flights what else every thing. No customer complaints perfect payments campare with other apps like mobikwik payzapp etccc. I preferred only paytm. And recently payment bank also added for merchants when you can use paytm app through barcode threat amount directly credit to our account but not immediately that will take 1 working day time but payment will come 100% with out any follow-ups. My small suggestion please add print option for merchants because when we will done power bills and other payments customers asking printed receipts. Thank you.
