Georgetown Interviewer Ghosting??

So I got an email from Georgetown Admissions to reach out to my assigned interviewer on Jan 4th. I sent an email to him on Jan 5th, giving the times I am available, where I am from, and suggesting local places we could meet.

I didn't get a response even by Jan 17th, so I sent an email to my local Alumni Admissions Program Committee Chair on that day about the situation (which was a mistake on my part since I def should have alerted them earlier). I got no response from the chair, but I then got a response from my interviewer on Jan 19th, so something must have gone through.

The interviewer responded, saying to text him about the interview. And so I texted him soon after I received that email. He did not respond at all, text or email, by Jan 23rd so I replied to his email (saying like I texted you, did you receive anything) and texted him again. I was being very respectful through all of this by the way! After I did that, he finally texted back, not confirming any details of the interview but only asking where I was located (which I mentioned multiple times in my very first email). I responded to his question like 2 hours after he texted back (I was literally in school so I could not respond right when the message was sent). He did not text back.

I finally texted him again yesterday, asking for more details about the interview and that I'm looking forward to it, and he has not responded yet. What should I do? Is this concerning? I didn't want to contact him on email again because he already told me to text him and made it clear that he low-key doesn't read the emails he is sent (because I put every necessary detail about my availability and location in my first email and he doesn't seem to be referencing it). I don't want to seem rude and pushy, but it's been almost a month since I initially reached out and in case you didn't know, Georgetown practically requires students to have an interview for their application to be considered fully. I don't want this interview scheduling issue to be a detriment to my application.

For all my other interviews, I've been able to get responses within a couple days or have the entire correspondance and interview be done within a week and a half. Idk what's happening. Might delete soon because I don't want my interviewer to potentially see this. Has this happened to anyone else?
