Hi jasonbudd1984
In my experience, the DWP often takes an inconsistent approach to what it says and what happens in reality. So, they may say you can send letters after the deadline (and you can), but they won't wait for them to arrive because they have no idea when you might send them in or how quickly they will be uploaded to the system. So if the person working on your case wants to complete it, they will, and any letters you send after that process won't be included in their decision.
