am I unlucky or the system is totaly absurd? or maybe I am the first foreigner to arrive to france??

I am a European citizen and started working in France in October 2022 (for an institution belonging to the state). Although my wife (who is currently not working) and I sent (actually brought it to the local CPAM) the application to get the social security numbers (SSN) together with the required documents on my first working day (I was told that it would make no sense to do this before it), we had not received them 5 months and a half afterwards. In the meantime each of us received one letter each asking for the same things we have already given them (ID copy, proof of residence) or could not provide (last pay slip, which I could not get from my employer because I had no SSN, while my wife is not working), and the English speaking hotline is either not working or not helpful (when I told them some diadem number from the CPAM letter the lady could not find it in the system). I have already worked in several EU countries and each time I got the health insurance card during my first week there. Moreover, colleagues arriving to France after us (also without previous connections to this country) got their SSNs in the meantime. Last time I discussed with the English speaking hotline of CPAM I asked for the contact details of the person in charge with our dossier and the lady on the phone was not cooperative at all. When I raised my voice to make her listen to me, she hang up.
Are we just unlucky, or the people at CPAM don't really do their work and the system is absurd?
