Tata Sky — No Installation even after 3 days

Hi Booked Tata Sky HD on 11th May 2015.Also full amount been paid. Till now No technician have called and visited for installation. Subscriber ID: [protected] Been calling customer care center for days, everyone saying they will send technician within 2-3 hours, but all fake. Such bad service never expected of Tata Sky. I already have Tata Sky connection at another location, Gulbarga, which is working fine and installation was done within 24 hrs. Bangalore Tata Sky team is utter crap at Customer satisfaction. HOPING FOR BETTER SERVICE.
