This company has been calling and harassing people...

This company has been calling and harassing people to pay up debt without any validation documents. If you ask for statement or letter from bank they will not respond. Every month they claim different amount of debt and their interest can shoot up to 20k in 2 months. Their agents behave like gangsters and go around threatening people. Please don't entertain this company and make a police report if they continue to harass you or fail to give you proof of the debt. If you decide to make any payment, please verify the debt with the original debtor first.
