Have been receiving numerous calls from this number. Managed to find out the name of the company and their purpose. They buy paper from telecom companies for pennies on the dollar and try to con you into paying the entire debt, thus making a tidy profit. Cross-referencing the name of the company, I found a mention of over 300 complaints filed due to their business practices. Whether true of not I could not say, so I don't want to impinge their "fine reputation"...
