After my third hold music session I gave up on phone menus and tried the web form instead. I submitted details of my stay, loyalty number and reservation code at
https://hilton-honors.pissedconsumer...r-service.html which connected me with an agent within twenty-four hours. The rep reviewed my account, manually adjusted the points balance and emailed confirmation of the correction. They also fixed the booking glitch by reissuing my digital key link in the same exchange. Having that direct online channel saved me from endless callbacks and finally got my loyalty account back on track.
