Tamil Nadu Electricity Board [TNEB] — unable to pay through rupay card

I am trying to pay eb bill through online payment with a rupay card. But there is no options for payment through rupay card. Also banks are issuing only rupay card to account holders throughout india. At this point it is very important that you update your server at the earliest as you are govt. Entity. Since many people depend on online payment and the rupay cards are being issued through out india, it would be highly appreciated if you act fast regarding this. Even if customers are ready to pay, they are unable to pay due to this technical glitch. Please do the needful at the earliest.
