Dear sir,
I have already paid the bill amount of rs 984 for the month of july-2017. But i have not receipt any money receipt, hence i request you please provide the money receipt at the earliest. And i will submit for reimbursement of the bill. Once again i request please provide money receipt for every month after payment of bill automatically.
Thanks,
