If they are who I think they are, we are talking about the company mentioned in the Arrears section of this site under "Debt Counsellors" at:(posted 8364 days ago)http://www.home- repo.org/arrears/debtcos.htm
I have heard the odd mention of them over the last three years but nothing specific.
You will be aware from reading the page mentioned above that I consider it unethical that they represent themselves to the public as mortgage debt counsellors while also carrying out a repossession shortfall debt recovery.
As for how to deal with them, you should exercise your rights as detailed on this site.
Good luck and hang in there.
