LG Electronics - Arrogant behaviour of salesman

On Saturday,** January, I went to the Vijay Sales store in Prabhadevi opposite to Siddhivinayak temple to complete my payment of LG refrigerator that we had already booked on *st of January . We had already mentioned the delivery date of our refrigerator to be done on **th of January during the booking day itself and we were very specific about it because that was our top most priority. On enquiring about the delivery status while making the entire payment, one fellow salesman was extremely arrogant in answering our queries. We demand strict action on such employees because such behavior is completely unacceptable. Amit Gupta from Vijay Sales, Prabhadevi was the name of the salesman who had zero etiquette to talk to us.
Kindly look into your staff or else we won't think twice on taking strict actions on this company. Also whatever the circumstances, we want the refrigerator to be delivered as mentioned on the booking day. We have our bill that shows the delivery date.
