Snapdeal.com — non delivery of product and false status updation

I Sri Amitava Chakraborty, had booked one Tata Swatch water purifier with order id [protected] on 12th nov 2014. Till today that is 10th Dec 2014 it has not been delivered. I have called snap deal several times and everytime they assured me that they will get back to me with a positive reply. But my repeated calls went in vain. Besides to my utter surprise the courier service is very much disappointing. Once i was instructed by somebody from snapdeal that i should take up with the courier company as the product lies with them.On calling the courier service they did not give me any suitable reply. And one fine morning when i was checking the status of the product it was showing me as "Item Delivered" . Whereas no such item was received by me. on further enquiry to the courier company they informed that it was mistakenly delivered somewhere else and they are trying to look into the matter.Few days later when i called up the courier company again, they replied the item has not been delivered it is lying with them somewhere and that they have updated wrong information. Now my question is that is it not the responsibility of Snapdeal.com to intervene into the matter? And what leads to this kind of negligence on the part of the courier company.All my phone calls was just wastage of my money and time.This case needs urgent attention and early settlement with a satisfactory reply from both snapdeal and the courier company.
