New broadband connection installed on 30th of june. And account activated on 1st of july but after activation getting the network speed less than 50kb/s some times in single digit. Raised service request nobody is ready to give resolution for the same even called to the executive they will discoonect my call.
So i'm very disappointed the ways of hatwya people. If you people's are unable to solve this issue. Please cancel the account take the modem back.
