So, you searched, and searched, and finally found this phone number at a site usually used for phone complaints.
But ... you forgot to tell us the company's address or website, so we could assure you were not merely shilling for some loanscum.

You also forgot that a phone call or an email is NOT sufficient notification, by federal law.

Settled my 2nd lien with them when they bought the debt from Bank of America.

This number corresponds to 469-549-2000 which is Nation Star.  This is a scam.  See pages of comments listed under the number I've given.
