Howdy,
i canīt comment on the specific repair and probably canīt help.
Thereīs a couple of possible reasons, from customs controls (which at times take 12 weeks to pass in Germany, with a comparable situation in Switzerland) over carrier delays to heavy workload in holiday times.
In order to check, it will need to know some details.
So iīd suggest to have a closer look at the situation by email.
Cheers,
