Tata Sky — refusal of services

my registered mobile no is [protected]-having mega hd in my 2 tvs. since one week there is no transmission in tata sky, i have called multiple times on help line number, the technician does not mention his name, and everytime we call, he says he is standing in front of my building and will be reaching shortly, however he has not come since 1 week. This is great inconvenience since we stay home waiting for the technician everytime and leave other important jobs pending.kindly look into the matter and do the needfull -DR ASHOK KUMAR
