Punjab State Power Corporation [PSPCL] — amount debited from bank account but receipt not generated

Address: KITCHLU NAGAR, LUDHIANA

On 09/07/2020 i paid sum of rs. 10540/- against my electricity bill having account no. [protected]. Payment got debited from bank account but the receipt never got generated. Its been seven days since i made the payment but the receipt has not been generated till today and tomorrow is the last date to pay the electricity bill. If the receipt is not generated the department will levy charges on late payment whereas i have already made the payment but the receipt is not generated neither the payment has been credited back to bank account.
Please look into the matter and help me.
Thanking you
