tôi muốn thông báo rằng: vì có vài căn hộ đang trong thời gian thay gạch, nên trước lịch hẹn 1 tuần, chúng tôi sẽ gọi điện xác nhận lại lịch hẹn 1 lần nữa với bạn
I would like to announce that: because there are few apartments are in time instead of tile, should schedule a week in advance, we will call to confirm the calendar appointment again with you
I would like to inform that: because there are few apartments in time instead of bricks, so 1 week before your appointment, we will call to confirm an appointment 1 again with you
