Oath ceremony will be scheduled

[EMAD301]

I attended my naturalization interview over two months ago. The USCIS officer there told me that I passed and would get a swearing-in ceremony appointment by mail. But nothing has come. Also the officer did not give me the form n- 652

I had an interview for citizenship on may 14th 2018, I pass everything and they told me that "decision canot be make " I never get call for oath ceremony (16 months) . I submitted several service requests and I never get any response, every time I got answer that I have to wait additional 90 to 120 days. I spoke with several higher level immigration officers and they do not have any explanation about my case, senator the same answer. There is no way anymore to go for infopass and speak with some officers and find the answers, there is no any email to file complaint with my local office.I really worry that my documents maybe have been lost.
