So I was supposed to do an interview on the 17th to keep my food stamps. I've called every single day and it always says they're experiencing high call volume. What do I do? I gave them all information they needed already, all that was left was this interview. And it's not the first time it's happened either! Last time, I didn't even get my benefits till the end of the month due to them not answering the phone or looking at my documents. What do I do?
