Please do not capitalise the first letter in each word when you post - it is very difficult to read.
You need to talk to your solicitor - you don't seem to understand the difference between signing the contracts and closing the transaction. If you cannot talk to the solicitor, then you can leave a message confirming that you do not want to sign Contracts until after Christmas. Ther may well be reasons why this will create difficulties - without knowing the facts, its impossible to say.
