In Delhi most people have taken Airtel(if they have option) instead of Mtnl, Mtnl staff attitude is a big reason.
Their plans are ripoff even when compared to mumbai counterpart. Most colonies are witnessing doscis 3.0 via den, hathway or Siti.
Mtnl is good if working , if you face any problem then god bless you rectifying it.
Though I have noticed staff of mumbai is much better than Delhi's. I have dealt with these ladies, lineman and backend staff for good no of years. Its like they don't want to learn or an ego factor ... how dare you teach us.
Thank god I shifted to a place where Airtel n Cable broadband are reliable.
