Hi davidjonesmosaic
There is clearly an error here - but you need to contact the DWP and confirm the date for the return of the form. No, they won't confirm any extension with a text.
You don't have to give any reason at this point - because they can't send out a letter dated the 6th saying that is has to be returned on the 8th. That's clearly nonsense. Normally people have four weeks from the date on the letter. This sometimes turns into three weeks as time is taken up for the letter to arrive.
