I finally heard back after reopening the ticket a week ago. Still nothing from my facebook post. So they're admitting there's a problem...
Please accept my apologies for the issue you have experienced with your Hertz redemption.
This is due to a technical issue which has affected a small number of members.
We are working to get the issue resolved and your points credited.
This should be rectified in the next 7-10 days.
Thank you for your inquiry,
Except 7-10 days is about 8-9 weeks after April 1
Also, this has to be more than a small number of members, given that not all of them are on FT, and several have posted they're also still waiting
