POSTAL MAILING ADDRESS FOR DIRECTV'S CORPORATE HEADQUARTERS

As a customer of DirecTV for many years, I need the USPS mailing address for DirecTV's corporate headquarters.  I have hearing issues and subsequently, do not talk on TELEPHONES...PERIOD.

Nevertheless, I'd like to write to Mrs. Laurie Giammona (Chief Customer Officer @ DirecTV) regarding a concern I have AS A CUSTOMER!!!!!  This means I need a mailing address to send her my concerns/issues about DirecTV for which, hopefully she will address and resolve...so that I can become a "happy camper" continuing to watch DirecTV.
