JustDial.com has the concept that they have huge database of registered all the local shops on their site which will help all the peoples in finding and contacting the shopkeepers !
I had an problem in my charger of phone and it was in waranty so I decided to go to service center but I didnt the the exact location and also the contact no. Of the service centers . I googled 1st result was with the just dial anf its shkwed up 4 to 5 service centers!
But the problem was that none of single contact no. Provided was right! All of them were wrong and also out of 5 results that justdial showed up only One was the service center and others were the sellers!
So if justdial updates its database regularly and have a sorted clisification then it will have good response!
They have the good concepts but they have created their database only once! After that many of the shops that have migrated, contacts have changed!
