After you file

My situation is a little odd. Ive had a payment date set for 4/15 then the site required me to update DD info around 4/21 so I did and it's been saying eligible for payment but no date available.  Here's the thing I've recieved a letter saying payment was sent to my bank account but in reality ive recieved nothing.  Letter was dated 4/15 and I got the letter 4/30. Am i just screwed or is there hope...ugh
