Sixt - Sixt Rentals poting HHonors points

I have had 4 rentals in the last couple of months with Sixt.

Ive added my HHonors number to each boong made through the website.

When I track them through the Sixt site it shows the 500 points as posted and says it may take a couple of days to appear on my account. but no joy over a month later.

The only ones that have posted are form my fist rental and this only after I chased customer services.

Does anyone else have any experience of this?
Thanks

Hi Dodda,

I rent a lot with Sixt. I never got any issue to get points posted to my hhonors account or Flying Blue account.
Usually, it takes 3-4 weeks to get them posted

From my experince, this can take up to seven weeks in certain cases.
