Asylum Interview

Does anyone has to give me any timeframe , i applied for asylum in Miami in 2017
I still didn’t receive the interview notice , my case has been pending for 750 days with USCIS , would anyone be able to provide me with any approximate timeframe of 2017 applicants. How many more years does it take ?
I talked to an USCIS officer on the phone this morning , i asked the timeframe for 2017 applicants from miami , she said probably we have to wait until end of 2021 or beginning of 2022.
