your details are slightly confusing.
if you drew down in nov 2005 the first dd would not have pulled on 1st Nov.
best thing to do is ring the bank, ring the mortgage centre, number should be on the statements.
find out the real drawdown date.
find out the first partial dd and first full dd.
get a cert of interest for all years 2005 onwards
and get a statement for 2005
if the funds were not released to you but the solicitor held them in their customer account, you possibly could have been re-imbursed for the interest charged on your account.
