I took out van insurance at the beginning of May and they request such data as DVLA access codes for all the named drivers, photos of licenses etc which I provided well in advance of the deadline. I then received a notice of cancellation for the policy in 7 days unless they received the data. I called and explained that it had all been sent and they said the DVLA codes had already been accessed and were therefore invalid. So I had all the named drivers do the same again and sent them all off to their unmanned inbox again. I received another notification of cancellation and they cancelled my policy, charging me £80 for the privilege. A lot of time and money wasted running around after their 'computer says no' nonsense.
