Where can we complain about my local (NYC) ABC station not having SAP?

Secondary Audio Program… recording Elementals on ABC OTA (on TiVo) since the feed on DirecTV Stream doesn’t have the SAP (description for the blind) I checked with two different friends with different Cable systems and they have SAP… and of course other channels have SAP like TBS / FX & other networks like NBC & CBS

This has been going on for over a month at least and phone calls and chat peeps just don’t cut it
