Hey all - I would appreciate some help, as I don't rent with Hertz super frequently.

On a recent rental, I tried to collect some Aegean (A3) miles on the reservation. The rental was booked directly with Hertz, and had my FF # attached to it and written on the agreement. The car class reserved was an ICAR, and I ended up taking an intermediate SUV instead from the UC lot. I did use an AMEX Platinum CDP on the rental. The rental was prepaid in a foreign currency.

4 months goes past, and of course, no points to be seen. I submitted a retroactive points request, and they say that the car class rented is not eligible for FF miles. I tried replying to get further clarification, and have not heard back in 2 months. I called in, and they advised me to refill out the request, which was again denied for the same reason above.

I tried contacting their social media team, and they are now saying that (a) my account was "not set up to earn FF miles" [despite my FF miles number/program being directly on the agreement, and set to default to that in my profile], and (b) my use of a CDP disqualified me from being able to earn FF miles, as they "can only honor one code at a time".

Can someone with more experience with this comment on whether any of the above is true? I can't recall using a CDP ever being a reason to not earn FF miles, as it's not a "code". Seems that nobody can help me and/or they just reply with minimal explanation.

Thanks!
