Payment Plan - no confirmation

Hello First time doing a SA! I set up a payment plan digitally a few days ago, but I've received no email confirmation and I'm unable to view any information about it. When you go onto the webpage I just see 'You already have a payment plan with HMRC'. I'm concerned with the deadline tomorrow if the payment isn't set up correctly or taken, I'll face a penalty. Could anyone who is in a similar situation clarify this? :)

Hi,

To check the payment plan has been set up you will need to contact our debt management team to review.
