They told me that my 1TB HDD which i recieved from the BTC offer is been dispatched and they will send me the AWK number(the number of the courier send throught the courier service) within 2 working days from 28th of august, 2015. they deducted even Rs.500 from my account which is the cost of the 1TB HDD offer. but though no any responce. It is been 4 working days still they have not send me any number, not even a single mail. i am really fadeup from the company's service. it is really very bad. even i called many times on the customer number provided by them, but there is no responce on it. please do something.
