Vijay Sales — Items not delivered on given date and misbehaving customer executive

Hi,
I purchased three items (1 AC, 1 Refrigerator and one washing machine) on[protected] from Vijay sales, sector 29 store. First at the time of billing the attitude of the person who was dealing with billing was very poor, he was not providing all the details about payment. Second we were promised that our items will get delivered by[protected]. Whole day passed, and when I called the store to get an update on the delivery, they replied in shouting voice that check the date on bill, your order will be delivered on the given date. This happened two three times when I called them around 4pm, 7pm, 8pm, 9pm. At last it was not delivered on the given date by Vijay sale. If you can not assure delivery on the given date at least you can reply politely but all the persons with whom I had a conversation were very misbehaving. I had the worst experience with Vijay sales though it was my first time and will be the last time.
