Guess what
Ive got ALL mine back as well (although only £495)...
They called me the other night and said would I accept £225, I said can I have it in writing...
Letter came (with letter to sign) and decided rather than bother with the post I'd call her up.
Called her and said Id spoke to the financial ombudsman, and I said I am not obliged to accept the offer.
She said "would i consider accepting anything lower" (

) and I said no.
SHe said OK, amend the letter she sent me to state the £495, and that I had spoke to her, and the offer letter will be changed
My boss, all he did was these following steps:
a) called halifax, said he wants his bank charges back, and got them!!
No statements, nothing
Needless to say he is now 1k better off...
