I have booked a tata sky set top box on 23rd of feb 2016 at around 10.30 am and my order no. is N0AKGE1 in the name of jayant saboo. They send me a message stating that, the installer will call you in 2 working hours. but i have not received any call or message from there side. After that i called up many a times in the customer service number and each time they have given me the excuse that they will call you in 2 hours. its been more than 24 hrs and till now i have not received a call as such. i have sent a mail to there email id [protected]@tatasy.com and my request number is N17IU52, but there reply was all the same that they will get in touch with me but till now i have not received any call from them.
