I made a payment of BBMP property tax of Rs.9424/- for the property ID 021-W0313-20-16 using HDFC credit card number 4617 8770 0014 4376.   The transaction debited the card.  But tax payment was not credited.  

 Details of the unacknowledged tax payment are as follows:

 I once again repeated the process and paid the tax and completed the transaction.   This time the transaction was completed and the property tax payment was acknowledged.
