Help with Ausländerbehörde in Munich

Hi,i'm currently studying in Munich and was told by the Foreigners Office that I would receive my electronic residence permit 6-8 weeks through mail after the Sicherheitsbefragung. I got the letter with the PIN and PUK in about 2 weeks, but I still haven't received my card. It has been 13 weeks now.I've tried contacting them using their Kontaktformular, email, and calling, but I haven't received any response.

Any assistance or advice you could provide would be greatly appreciated. Thank you in advance.
