create window cmd batch file to automatically retrieving data form SFTP

I am trying to create a .bat file which connect to the SFTP site with SSH key and pulling data file once a day.
-------------------------------------------------------------------------------
REM Connect to Concur SFTP

REM SET MyPath=C:\Program Files (x86)\WinSCP\

WinSCP.com sftp://p0092028qn3w@st.concursolutions.com/ -hostkey="myhostkey" -privatekey="C:\Users\xxxxx\Private_key.ppk" -passive = off

get *.pgp
-----------------------------------------------------------------------------
I was able to connect to the SFTP site successfully. However, the script doesn't execute any other command line after it was connected to the site. It opens a command prompt window "winscp>_" and waiting for me to typing the next command line. Then, if I start typing "get *.pgp", then all the files with that extension will be retrieved. How to I bypass the popup command prompt window and force the script to execute rather than manually entering the next command line? This defeat the purpose of automating the task.

I even created 2 separate files (.text and .bat). The .bat files called the .text file, but it still doesn't work. Also,try using winscp.exe with open command, but no luck.

Thanks...
