Omnishambles
I was on this Beast this morning as my partner is attempting to claim benefit and as they now base benefit on entire income, I had to register as well.
It went relatively well until it came to the ID verification part: the Government has nominated a number of external, familiar organisations who will ask you questions and require documentary info to complete your registration. They also need you to have a debit or credit card so they can "charge a zero-amount to it". Then you get passed back to the Beast.
So it assumes that you have a mobile device that can install apps :-) We told it we had a passport and driving licence and duly entered the info. Then it asked us to install an app that would scan an image and send it to, erm, somebody. Mobile #1 Android version was too old to run the app. The online form said "can't install apps? Borrow someone else's phone" (!) FFS.. so I offered mine, and installed the app.
It said to photograph the passport page and this is where the fun started. With recent passports, the relevent page is covered in a shiny, semi-holographic film that simply cannot be photographed. To make it worse, the passport image had to be lined up in an overlay box, as did the text at the bottom of the page. No, of course it doesn't line up, and 30 attempts later I still couldn't get the required image.
In the end we registered with a different provider and didn't need to scan anything.. The ultimate irony is that once you've scanned everything in (if you can), you have to go the Benefits Office to show them your ID that you just scanned in anyway!
Omnishambles is the only word I could think of and really it doesn't do it justice.
