I have also received a "printing error" letter. In mine they are changing the original 0% interest free period from Nov 09 to May 09 - effectively cutting the period down by 6 months. I have all the original papework letter and agreement clearly stating Nov 09. In a telephone call last year they tried to tell me it was May not Nov - and I told them they were wrong. Printing error or not, they made an agreement. The must be a hel f a lot of people affected by this underhand action.
