Kendriya Vihar, Sector -82 specifically and Noida generally, don’t take a World Phone connection. If things go right they may go right but once it rains it pours. You internet speed will decline and all of a sudden you would be calling customer care everyday which always puts your phone to voice mail.
Customer care execs are bunch of Idiots and their engineers much more so, they would give the stupidest reasons in the world.
