Department of Revenue is shit
Hi! I called right at 8am, was on hold for 30 min, then was able to get through. I suggest you do the same. They told me that my check had indeed been sent, but it was returned. They put in a request for it to be mailed again. Apparently it’s been happening to a lot of people - the mailing address is correct but USPS will still send it back. They suggested I reach out to my local post office and make sure I’m a verified resident. More on reddit.com
