Renovation Disappointment

We have been having some window/home renovations done lately at the house, all was going well at first and they had probably 90% of the work done in the first 3 days. They hit the snag when they went to do the siding and realized they had ordered the wrong siding in. It has been 2 weeks since they were last at the house and we are hopeing they will be back this week to finish up. It is frustrating because the front of our home has no siding and they had a few things inside to finish up that are waiting too so our kitchen is in turmoil. The good thing, we don't have to make any payments for the job until the work is all finished so everyday is one more day until I have to pay but it would be nice to finish it up.
