The best was that certain sections were circular, so it would start to ask the same questions again but displaying answers prefilled in - yet it would arbitrarily forget particular (different) details on each loop, defaulting to values other than what you'd entered before, so there were only certain points you should exit the loop at, to be sure it would submit the right information!
On the plus side, despite their system woes, they had very competitive rates, so it was definitely financially worth spending another 20 minutes and accepting their idiocy!
