Hertz took 39888 points from me as supposedly expired. This, just two weeks after a Hertz rep on Twitter affirmed that I had no points at risk of expiring in the coming months. I expect that they'll restore the points when pressed. But what a waste of time this company is. Wish it were easier to redeem my balance down to zero and of course never rent from Hertz again.
Meanwhile the 39888 number is definitely NOT the number of points I earned >5 years ago. That's 99% of my balance, but I had plenty of points-earning rentals within the last 5 years.
