Mortgage Update

I'm about to write a not-so-nice review of the mortgage company with which we are dealing. Today, they decided that they needed a couple of cancelled checks. That's all well and good, but they didn't know that they needed these items last Friday? Not only that, but the broker said that our account was with the lender's lawyer and in the final review process, which is obviously untrue if the underwriter is still seeking information. We were told that the clear-to-close (which, last week, they assured us would be Friday or Monday) will not come today (Tuesday). It looks like we'll be here another weekend. I'm getting very frustrated and discouraged.
