I have received an arrears bill for Rs 1177/41 which shows that I have defaulted on payments of two bills for months of October and December 2023.
The fact is i have made two payments by cheque against these bills and the receipt of these payments is reflected in my PNB bank passbook.
Here are the details of payments made:

!. Cheque No 693075 on PNB dated 2/12/2023 for Rs. 607/ and received on 14/12/2023 by your office as shown in my passbook.

2. Cheque no 693079 on PNB for Rs 607/14 Showing receipt in your office on 26/12/2023.

So I have already paid Rs 1214/14 against the arrears bill raised by you of Rs 1177/41.
So no arrears are due to me. Kindly check your records and confirm on my registered mobile no. [protected]. I don't have any online facility. So kindly convey the resolution of my complaint on my mobile/whatsapp.
Thanking you
