Advice needed please guys. Here's the timeline of my RBoS claim so far: Original claim made for £2,xxx.xx in December 06 but made an error in the claim amount, although not spotted until early Jan. Letter from RBOS "We are reviewing your complaint etc" early Jan Revised claim letter for £3,xxx.xx sent in 10th Jan 07. Offer letter for the original £2k sum received 22nd Jan, signed and returned. Payment in my account by 26th Jan, GREAT I thought! Offer letter for my revised £3k sum received today with different reference numbers! DO I SIGN AND RETURN or own up, call them and explain the mistake. There's about a £500 difference between the 2 amounts, but i wondered if I can get away with the line that I assumed they were sending me a revised figure and happily accepted?! Or by accepting the "full and final" offer earlier in January am I not entitled?
