Removing a value from Firebase Database

I am trying to remove a value within the Firebase Realtime Database. Here is the code I am using:

FIRDatabase.database().reference()
           .child(FIRAuth.auth()!.currentUser!.uid).child("instagramLink")
           .removeValue()

Here is the JSON Data Structure:

Users {

    userUID {

        email: "test@test.com"
        fullName: "John Doe"
        instagramLink: "testLink"
    }
}

I am telling the database to remove the key "instagramLink", which I know is currently in the database, but the key never gets removed.

How do I remove the key?

Extending to @cartant's answer , this way you will know if you run along any error during removal or if the value's were removed successfully or not.:)

FIRDatabase.database().reference().child(Users).child(FIRAuth.auth()!.currentUser!.uid).child("instagramLink").removeValueWithCompletionBlock({ (error, refer) in
if error != nil {
 print(error)
   } else {
  print(refer)
 print("Child Removed Correctly")
}

It looks like you've left Users out of the path:

FIRDatabase.database()
    .child("Users")
    .child(FIRAuth.auth()!.currentUser!.uid)
    .child("instagramLink")
    .removeValue()
