US citizenship Interview

I appeared in my scheduled interview for US citizenship, when I arrived to federal plaza uscis NY, they said they don’t have my file and USCIS center failed to send it. The officer keep my notice and told me that it is the evidence that I appeared in my supposed interview and I have to wait for another letter. It's been two months but until now I have not get any notice. Is there anyway to follow up on this? or any similar experience?
