Tata Docomo prepaid and Tata Indicom postpaid is providing worst service in the sector, compared to any other service provider in Panjagutta. Calls are getting dropped in between, GPRS is unable to connect, network strength is wavering each second. Complained at least 15 times from each phone of 5 here and having connections 10+ in my stay. Customer care assures each time by some reference number claims that it will be clear in 24hours/ 3 days and still the same persists.
