For the last 2 months the Internet speed is very low & sometimes no connection at all. When I visited the Tatadocomo Store at City Center 1, Kolkata to complain about the same, the service Representative rudely said that they can't help & if I wish I may disconnect the service. What an excellent SERVICE!
