Dear Ankita ,
The amount gone is not more than 406 Rs. I suggest you to let it go. Because the procedure to claim that amount back is hectic and time consuming also require too much written communication.
Although, if it is necessary you have to write a letter to ESIC area office about the same for claiming the amount. If you don't get any reply from them, drop one more letter to the same office about you deducting the same amount from the next month's challan amount. and pay that much amount less in next challan. but please keep that written communication filed till forever as you will be needing it at the time of inspection.
