Calcutta Electric Supply Corporation [CESC] — Bill payment done money deducted but receipt not given still showing payment option

I tried to pay my electric bill and paid 580 INR for December bill. This time also money was deducted and payment from my SBI account was shown successful. But then browser showed some error. I again checked but found that receipt of payment is not given in cesc website. It again gives the option to pay bill instead of receipt when I entered my consumer Id. Details of transaction:
