Then I would suggest to call again later during German office hours in order to make sure, that you really talk to somebody from LPJ. During off hours, you may get diverted to one of the 'normal' call centers, which are reportedly - well - not always 'the distinct source of truth'.

At least on Monday, I still got a written confirmation from LPJ, that the additional miles count as status- and HON-miles as well. Also today, there were apparently multiple sources confirming that. If you can read German, please check the according thread on VFT for this.
