I am having a karvy account with Begumpet Hyderabad branch. When I open account I am aggressive and had done trading. After few years with Karvy, I really hesitate their service.
They are user unfriendly, you need to roam around their offices to just change your address if you relocate to other location. They ask hell lot of documents if you plan to close DMAT and their Karvy account. Not only that, if you dont provide they will simply say, if you want to close, that is the procedure, else suffer with Karvy.
I hear this from one of the representative from Karvy.Rules of thumb, as long as they hold DMAT and Karvy account they will get money because of Annual Maintenance, etccc.
