Convergent Outsourcing has sent me demands for payment (and called me) on a T-mobile bill that I supposedly owe. I've been a customer in good standing with T-mobile for +15 years.
I do not owe them any money, now or ever. When I called T-mobile about it, they said "Ignore it". T-mobile had no record of the T-mobile "client account" number provided by Convergent, and failed to recognize it as one of their own. T-mobile indicated they've received similar complaints from other consumers about Convergent.
I called Convergent and told them: 1) to stop calling and contacting me, 2) no debt was owed, and 3) remove me from their system. Convergent replied they could not do so until the debt was paid.
Convergent appears to be a fraudulent company, attempting to collect on non-existent debt. I've since written the Attorney General of the State of Washington to complain of Convergent's illegal business practices and harassment.
