go talk to immigration. In your situation with a Thai wife, and take your wife with you, they are very helpful, and will do what needs to be done so you get the extra 7 days needed, and more. They can make exceptions and give you extensions when they want to. In years past, in a very similar situation, I was given an extra 30 day extension when it was taking a long time getting the documents from the property owner where I rent. Go talk to them with your wife. They can be very helpful, and take your bank statement so they can see the problem, and that you do have the money.
