Hi Ellz
You need to complete the To Do as if it is ignored it may create an automatic block of your next payment on the UC IT system.
The UC Journal is for communications between the claimant and various DWP staff. Sometimes owing to backlogs and staff absence they may not be answered at all or answered only after a long wait.
Let us know how you get on.
