Is there anyone worked in the office and reply my question? I asked the schedule over three weeks but still no one feedback.

"Is there anyone in the office who can respond to my request? I asked for the schedule over three weeks ago, but I have not yet received a reply," This is, perhaps, a softer way of putting it; it's better grammatically, as well.
