How very typical of IDES to make this kind of mistake! Have you received any benefits yet? If this was just a mistaken item added to the mailing envelope, don’t try to contact them. They NEVER fix their own mistakes!
But if you aren’t getting your benefits in a reasonable time, try reporting it under identity theft on their site. That opens up an entire new set of problems as they can’t get their act together there and may stop the entire process of your benefits. So wait a while to see if your checks or direct deposits come through!
