My electricity bill payment order ([protected]) on april 28, 2019 at 8:15pm was failed but amount was debited from my bank account of rs. 50. I haven't got refund yet almost 9 days over. Your customer care was not responding properly they just saying check it on 24x7 in the paytm app.
Now the failed order was removed from my order list but i have screenshot of that order and i have bank transaction id.
When will i get my refund?
Bank saying it was paid they were giving transaction details (Medr/paytm/563233)
