Re: Probably a rubbish question
There is no such thing as a rubbish question, only a rubbish answer.
Start bluffing to your bank. Ring them and tell them that you have approval from another bank and thet they have guaranteed that paper work will be available in x days. One step ahead would be to actually go to other lenders and ask if they approve you and if they can have paper work ready by x date.
Also ring the manager of your branch and tell him the same thing. It worked for a friend of mine after threatening 3 times, upon which the documents were hand delivered to his solicitor in a matter of a few hours.
