In recent times there have been many webservices coming up in the state of Bihar who are trying to extract money out of the pocket of innocent people for just simple listing of their business or enterpirse on their classified. Its disgusting to pay money for going online. One such service which regularly advertises in local Hindi Daily claims that there is no need of website because they will provide membership to bussinessmen in their classified.
It is an honest suggestion, don't ever pay for listing in online classifieds unless they promise you and provide you an online interface where you can find if the listing is going to help your business to grow.
Besides that check the website rank of those serviders, if they don't feature in the top 1000000 ranks of http:alexa.com most likely they are run by inefficient frauds who are trying to extract money without giving any sort of returns.
If you have been fooled by any such services do complain against them.
