KARVYONLINE is the worst service provider. When the entire world goes paperless these idiots have glued themselves with age old Paper work.
When you open an account with Karvy, be sure they will update your profile with a wrong Email ID or Mobile no. and afterwards they will harass you like anything to change these simple things and the customer care representatives are the most DUMB creatures for sure. Every time they will give their horrible excuses and expert advises which will only be harassment for you!
Again, they change their trading portal so often that you will be pissed off!
