How to approach bad communication with my department I am a mathematics student at a top 10 math department in the US.  Something I have been struggling to handle is an on-going situation I have been facing with with the administration.  

When I was accepted to this university I was instructed to submit the syllabi of the graduate courses I had taken at the institution I came from.  My initial email to them was in the beginning of this year.  After 1 month without hearing from them I sent another email following up.  The third email was done in the beginning of April with again no response.

I have tried to reach out to different people within the department, but I have gotten no response.  As emails are easier to ignore, I tried going to the administrative office in person.  The receptionist said that they were not accepting walk-in appointments and I should try emailing them.  I explained to them the situation, however the receptionist would not budge on their stance.  

As this situation progresses I am getting increasingly frustrated and paranoid about my treatment.  These issues I did not experience at any of my previous universities.  As such, I am kindly requesting if someone has any suggestions or experiences on this matter.
If your department is like any other US math department I’m familiar with, it will have a graduate program coordinator (or similar title), a graduate program chair/graduate vice chair, and a department chair. The first two on this list will usually have office hours you can visit to talk to them about any issues you need help with. The department chair ought to be available to talk to you, either as a walk-in or by scheduling an appointment, if you have failed in your efforts to get one of the first two to listen. Through some combination of email, phone, showing up in person and knocking on doors, and gentle assertiveness, it is difficult for me to imagine that you will fail in getting someone to hear your concerns and work out a solution.

Good luck!
