The irs says it was sent to my bank account feb 27th

Is that what you see when you use the IRS "Where's My Refund" tool?

https://www.irs.gov/wheres-my-refund

If so, the IRS says to allow up to 5 days due to variations in bank processing procedures/times.

Or did you choose this option?

If you chose to pay any product fees out of your Federal refund, the funds go first from the IRS to an account at an intermediary bank where the fees are subtracted.   Then that intermediary bank sends the rest to your bank account (or card.)  The company that handles that is called SBTPG (Santa Barbara Tax Products Group.)

If you DID use that payment option, and if you're sure the IRS has released and sent your funds, you can log in to your temporary account at SBTPG to see the status of your funds.

If that's your situation, then to log in, choose the "For taxpayers" portal at:

SBTPG also has a phone contact page at the following link. It also shows their business hours.  Even when they are closed, you may be able to get automated info, or you can log in as above.
