Payment Plan disapeared from my account after first payment

Hi. I have set up a payment plan for the 2022-2023 self-assessment tax payment. The first payment was taken from my account via Direct Debit on February 1st. The second payment was due on March 1st. However, I have now received a letter from HMRC stating that my entire tax amount is overdue. When I check my account on the HMRC website, it does not show my payment plan, and when I attempt to set up a payment plan again, it says, "You cannot set up a Self Assessment payment plan online because your payment deadline was over 60 days ago." What can I do now to reinstate my payment plan as it was originally arranged?

Hi 

You will need to contact the debt mamangement department to review 0300 200 3382 Monday to Friday 8am to 6pm.

Thank you
