My Bank of America mortgage got sold like a cow ready for slaughter to this weird company. After a couples of months I started receiving a lot of phone calls.
I had to put a fake phone number on my account because they kept calling me to refinance my house. Very aggressive caller and even when I said I didn't too and change my phone number, they kept sending me refinance offers by e-mail and overnight by FedEx. It took 4 nasty e-mails to make them stop.
Their website is one of the worst to deal with, when it actually lets you in. Communication with them is very treacherous.
