One of my Citi mortgages that was negotiated (ugh), was subsequently transferred to this company called Mariner Companies.  

Has ANYONE worked with them and what is the story with them.  They have no website so I cannot find any contact info.

Linkedin has several Vice Presidents etc but I cannot find concrete information on how this group works or anyone to complain to!

Then the sale amount Citi agreed to, they will not and want $15K more. 

Anyone out there know these folks and can give me some insight or help.  Thanks.
