I'm getting a steady stream of actual surveys- usually qualify for and complete one per day and the credits post in a day or two.
Still having an issue with the occasional survey that collects way too much info before kicking me out. Last month I sent Customer Service a note on two specific surveys, both with enough info to identify the company behind the survey, and got only an e-mailed robo-response. That's new; typically a human got back to me within a few days and provided credit. I hope that was a one-off occurrence.
Hilton points still VERY slow to post; reward requested 5/28 not in my account yet.
