It is useless to call IIO if your case is not old enough
Just wait for your luck or check the status at night. Do not waste your time. I know that you have the right to do so. But, you block the lines, so those desperate ones can not get through. You should know why you have to keep dialing over hundreds of times and hold the line for a long time. I heard that every time you call, IIO puts a note in your file, so processing of your case may be delayed.
