That’s poppycock. Especially as the DWP now use an online identity checker, Experian, post office etc to confirm the identities of all new applicants for UC and the like!!!!
Absolute d1cks they are.
I can’t remember and can’t get downstairs right now but doesn’t the award letter have your DOB on? Have you anything official from any of your claims with your DOB on?
Also, don’t fall for the “PIP systems are different to any other claim Systems” malarkey, I never did see the point of calling DWP & erm DWP (JCP (PIP)) to change my address. Funny how all letters from JCP and PIP come through!
Call again. Hopefully you’ll fall on a more sympathetic ear.
