I had complaint yesterday about non credit of rs.8911.41 twice debited from my sb account while paying electricity bill to mgvcl on 12th october 2018. No actions are yet advised to me. Please advise me the status of my complaint as well as refund of 8911.41. It was advised to credit between 7 to 14 days however not yet credited. I approached my banker however told to approach paytm. Not able to connect with paytm people. Can help me out of this.
