What sort of Electricity Board is this?

The Ceylon Electricity Board keeps sending a red notice for dues over 10000 rupees to a customer, because a payment made on the 1st of July to the CEB for Rs 8,750.00 has 'disappeared.'

The payment was made via HSBC, which has given a written statement with the HSBC frank on it, that the payment was made to CEB, and to the proper and relevant account number.

But the CEB has not acknowledged the payment, even though payments made later by HSBC to the same account have been recorded.

This means the payment for 8750, the 'big amount' disappeared. Who vanished with the money? And what audacity, to send red notices with threat of disconnection to the customer, when somebody at CEB seemed to have 'vanished' with the money?
