reniging on their original in writing application from 7/6/2012

Hi,  BOA,  has had us locked into a mortgage refinance at something like 2.3% at 15yrs since 7/6/2012.  Suddenly, in the last week or so they said we need to close this out right away.  Not only did it jump from 109,000 to 113,000 plus higher payments than we already have. They're actuallly threatening us as of today that they're going to close out the loan if they don't hear from us.  After sitting on this for months.  In a matter of a couple days they want us to say yes without any paperwork!!!!   This is not right.  I should call my lawyer, because this is ludicrious!
