Kolkata, West Bengal, 700031

I purchased one panasonic AC model No. CS-KC18SKY3R/1.5 Ton from 19/2 Garia hat (south) Branch, Kol - 31. Invoice No. DK/SA/1718/00042 dated 01.04.2017
The delivery date of which is 03.04.2017. Full day we are waiting for the delivery . we cant go out. but at last not delivered the item. It is fun how you are putting date of delivery if you don't have such infrastructure. During purchasing the sales person Mr. Sabyasachi chatterjee assured me that installation will be done within 05 days. why such assurance are giving to the consumer to harass them. kindly deliver my item immediately or refund my money back.
