I didn’t get paid?

I just got off medical leave for major surgery last week, the 20th. Yesterday was supposed to be payday. My paycheck didn’t hit, which is normal sometimes, it’ll come a day late and be on Thursday. But I still didn’t get paid. I was supposed to have 3 weeks of coverage plus my PTO. I didn’t even use up all of it. There’s no reason I shouldn’t have been paid. Should I call Sedgwick, or should I call walgreens? I don’t know whose issue this is.
