A broadcast receiving device and a reporting method thereof are disclosed. If a request to purchase a pay service is received, a signal received from a remote control device within a preset reference time period is sensed before purchasing the pay service in order to determine whether the purchase is normal or abnormal, and a purchase questioning message according to the determined results is transmitted to a pre-registered contact number or an address of a user and a time display unit mounted on the broadcast receiving device. Therefore, if a pay service purchase request command is received, it is determined whether the purchase is normal or abnormal by sensing a signal received from the remote control device within the first reference time period set before conducting the purchase, and a purchase questioning message according to the determined results is transmitted to a user's pre-registered contact number or address and the display unit, which is mounted on the broadcast receiving device and displays the current time. Accordingly, loss resulting from abnormal purchases can be prevented and successive abnormal purchase can be eliminated.
