Bangalore Water Supply & Sewerage Board [Bwssb] — bill already paid(rr no n-234732)

I have received water bill for the month of August for amount of Rs 988. Whereas I have already paid previous bill of Rs 696 for the bill 690 vide paytm order number [protected] on 02 August 2019. But this month bill reflects previous bill of Rs 690 as previous bill not paid with added amount of Rs 988 is received. Please look into this matter as we already paid the previous month (picture attached for your reference) bill of Rs 696.

RR NO is N-234732
