USAA Savings Mortgage Complaint

USAA Savings Mortgage department,

Conventional fixed mortgage Application, originator, mortgage broker Virginia

I obtained a home mortgage through - several years ago. My mortgage was recently sold to Nationstar mortgage. I received a notification by mail that Nationstar will share my personal data such as my social security number and income, my account balances and payment history, and my credit history and scores with other business for marketing and information purposes and I can not opt out. This is a company that I did not choose to do business with. I do n't want my personal information shared by a third party. I do not believe that this should be allowed. Please advise.
