Oops, I did it again

Paid twice for an online bill, that is.

This time it was with Airtel. The first payment was through my credit card; the transaction was not approved for some reason. I waited a day, and made the payment again, this time through my bank account. Later, while reconciling my credit card statement, to my shock, bewilderment, astonishment, and indignation (who am I kidding? I half expected this to happen), I found an entry corresponding to the 'failed' payment.

Airtel has excellent customer service. It took just one phone call for them to acknowledge the double payment and assure me that the second payment would be adjusted against my next bill.
