Just Dial is a well known for its free service. Nice concept!
My personal experience with this telephony service is not good though.
The point I would like to mention here is getting misguided. Several times when ever I asked JustDial, I was provided with Some Wrong information. with wrong address or contact no.
Yes, this wrong information costed me in terms of money and time.
They really have to make the service better and update their database with correct information.
They are too much in adverting and poor in service.
one of my friend told me that Justdial.com offers poor services to its advertisers.
