I have a degree from a university in Germany, which I'm now trying to get evaluated by an institution in another country. This institution requires that the transcripts be sent directly from the university in a sealed envelope. Unfortunately, it seems this isn't something that German universities are wont to do (or at least not my former one): I have been told that presenting my original Urkunde (diploma) is enough, which is completely false in this case. Is it possible to get a sealed copy of my degree certificate and transcripts from a German university, and, if so, how/where do I do it?
I have been in contact with the Prüfungssekretariat (something like an "exam office"), and they told me two weeks after I first asked them upon me asking them again that they "currently don't have access to" these records and that I probably should have a copy of my records be "beglaubigt" ("notarized").
I then contacted someone at the university in charge of Beglaubigungen, who offered to do so if I send them a copy. However, they have not responded directly to my request to have them sent in a sealed envelope directly to the institution in question.
I called the Zentrale (central hotline) and asked what I should do in this situation. I was then told I should contact the Studierendensekretariat ("registrar").
I have literally spent the entire afternoon trying to call multiple different numbers for the Studierendensekretariat and they do not answer the phone. I have sent them an e-mail, but, based on my previous experiences with them, I do not expect them to answer timely or even at all. I am currently over 1,500km away from the German institution in question, so dealing with this in-person is not possible. While I was at the university, the only way things could actually get done is by going to the office you need during their opening hours (which are only a few hours and only on certain days) and then waiting for an extremely long time. Sometimes, the office would close before you get a chance to talk to anyone†.
† Yes, this is a lot of circumstantial information, but this is, according to my experiences, fairly normal for German bureaucracy. Hopefully, however, these details will at least be useful to show at least what I've tried which hasn't worked.
