                Return Ok(customers)

    End Class


    Public Class Customer
        Public Property Account() As String
        Public Property Expressed() As String

    End Class
End Namespace

this runs well 

http://127.0.0.1/KABOJJAAPPAPI/api/HandlerVBLoadterm/GetCustomersJSON/0782911364/Father

and it brings this data 

[{"Account":"19-07561","Expressed":"END TERM 1 2019"},{"Account":"19-07561","Expressed":"END TERM 2 2019"},{"Account":"19-07561","Expressed":"END TERM 2 2020"},{"Account":"19-07561","Expressed":"END TERM 3 2019"},{"Account":"19-07561","Expressed":"END TERM 3 2020"},{"Account":"19-07561","Expressed":"MID TERM 1 2019"},{"Account":"19-07561","Expressed":"MID TERM 1 2020"},{"Account":"19-07561","Expressed":"MID TERM2 2019"},{"Account":"19-07561","Expressed":"MID TERM3 2019"},{"Account":"19-07780","Expressed":"END TERM 2 2020"},{"Account":"19-07780","Expressed":"END TERM 3 2020"},{"Account":"19-07780","Expressed":"MID TERM 1 2020"},{"Account":"19-07781","Expressed":"END TERM 3 2020"},{"Account":"99-00004","Expressed":"END TERM 2 2020"},{"Account":"99-00004","Expressed":"END TERM 3 2020"},{"Account":"99-00004","Expressed":"MID TERM 1 2020"}]
