CB ESA appeal-NEW MEMBER Help-Advice-Direction

Hi New Member looking for Help-Advice and Direction
In very short, April 2023 DWP online application for contribution based (CB) New Style ESA made online with supporting evidence attached. Despite chasing no response from DWP-sent complaint letter to DWP in December 2023.
End of December 2023 received DWP letter stating my claim was not valid. I have chased the DWP up via letters and emails requesting that they provide me a decision notice, statement of reasons and resolve my complaint including paying backdated CB ESA and compensation. There was then no DWP response to numerous emails and letters that I sent.
In April 2024 a DWP letter was received that admitted that the standard of DWP service that they had provided was unacceptable, the DWP apologised and upheld my complaint. Despite this the DWP have done nothing to remedy or rectify my complaint-No CB ESA or any compensation payments have been received. I have furthered my complaint to the independent case examiner (ICE) and am awaiting an outcome but I am unsure what the ICE powers and jurisdiction are.
Again, after further months upon months of DWP chasing emails and letters that in the main were not responded to and without receiving any copy of the requested DWP original decision or a statement of reasons, a mandatory reconsideration notice (MRN) dated 27 Jan 2025 has now been received.
The MRN now says that on 15/05/23 a decision was made that you were not entitled to (NS ESA) as you had not signed a Claimant Commitment. The MRN then quotes that the law used to make this decision: 1) Welfare Reform Act 2007.Section1 and 3, and 2) Social Security Contributions and Benefits Act 1992 Chapter 11,schedule 12.
I have emailed DWP for a copy of their alleged decision of 15/05/23 that they now claim to exist and have been unable to produce a copy of and a statement of reasons for their decision-there has been no response to date.
To date there is no DWP evidence of a DWP alleged decision dated 15/05/23 and there is no DWP evidence of an alleged DWP claimant commitment.
It is my intention to appeal via an SSCS1 -if that is my only option-I would appreciate any Advice-Help-Direction with this and in particular with section 5 -reasons for your appeal.
It is my understanding that I may be able to claim CB ESA payment pending appeal (PPA) but I cannot see any DWP forms or advice on this procedure.
Thanks in advance.

Thanks for your reply- To date I have not been invited to or seen any claimant commitment; The first mention of a claimant commitment is in the MRN of 27/01/2025. If the issue is the alleged claimant commitment, could not the DWP completed online and/or emailed me same?
Can I or how do I claim Payment Pending Appeal?
Do you know of any reasons for appeal in this matter that could be argued?
