The tariff is not fixed for all areas in Kolkata, I pay 612 INR Haridevpur area for silver while a friend who stays at DUM DUM phari pays 550 for the same.
On questioning the local provider he claims of adding some hidden charges, apart from the service tax, to the tariff I was absolutely unaware of.
The customer service was a horrendous experience, the executive I spoke to was an airhead with no knowledge about the service wishnet provides.
The wishnet site itself is inadequate in providing the details for the tariff and packages, the local service provider offers more packages as seen on the site.
The site does not include tax for different packages price thus giving the the local service provider the freedom to set prices to his benefit.
