I had paid online bill for account number z74zk611044p on 8 aug 19 at 21.38pm by netbanking trough my sbi account. Amount of 2110 was debited from my saving account. I got sms of amount debited towards payment for pspcl. But no reciept generated. I mailed and called 1912. But they asked me to wait for 48 hours, which i did, still it is not resolved. Kindly do the needful.
