Still pending bank repayment for overpayment from tax return

Hello, Overpayment from tax return for tax year ending 05 Apr 2023 is pending even though its due date was 31 Jan 2024 (yesterday). I completed my self assesment tax return months ago in November 2023 expecting to receive repayment back — however, it looks like it is not happening. What would be the best action at this point? Should I wait for a couple of more days or is there a place where I could contact an HMRC official for an inquiry? Thank you.

Hi,
If the repayment is still pending then you will need to contact HMRC to review:

Thankyou.
