Tata Sky — No service since last 5 days , customer care not picking up call

Its with heavy heart I'm saying that I am very much disappointed from the kind of service your company is giving to customers. My subscriber id is [protected].Customer since last 5 years .Since last 5 days trying to raise an complaint that my set top box is not working.With great difficulty got to talk customer care (in my 14th or 15th attempt).They gave one number for sending sms or give miss call did both getting reply on sms that your number is having multiple subscriber id.Now don't know how to register the complain.looks like have to stop using and go for some body else.
