Missed deadline - ESA account closed

My father missed deadline to submit bank statements, due to broken device he didn’t get email notification to check journal. I handle his affairs and didn’t receive a text message to check the journal. We have also been dealing with a family bereavement. Due to my father’s mental health issues, it would be too stressful for him to go through ESA application process again. I logged to to DWP and his account was closed on 16th April. Do I have grounds for mandatory reconsideration? . I have the evidence - bank statements that were requested and housing information

Thank you. It was actually the UC account that was closed ( all so confusing) . I contacted UC a case worker contacted me back to do an MR and bring documents to job centre. He said to do a rapid reclaim and LCWRA would be added back to the account. I went through UC questions and I’m stumped on HEALTH: Do I tick fit note ( and wait longer to go doctors etc) or select a date his health affected work, I wasn’t sure if the date would be when my father started to hand in fitnotes or can I put a random date when ill health started to affect him where he shouldn’t have been working or looking for work ( it’s been a longtime, I don’t know the exact date) he shouldn’t have been working way before he got benefit. My father is concerned that if dates don’t match up ( somewhere on UC system) there will be an issue.

I can’t access journal until I submit the claim, so I can’t get anything in writing. I will call back and see if I can speak to case manager. I called the hotline and they said if I don’t have a fitnote I should put in the date the health impacted my fathers ability to work.
