Punjab State Power Corporation [PSPCL] — Not receiving any notifications

I Have registered my email id and contact no to my PSPCL account. But still I am not receiving any notifications about the due date of payment of my bill. Currently I am living out Punjab and cam not go every month to pay the bill offline thats the reason I makes online payment but I do not receive any notifications for reminding me about it due to which sometimes I forgets to make payment. I want to get notified about the date of payment.
kindly help
