PS - where has the builder gone?

BTW, the builder is just as difficult to get a hold of! We had the 90 day check about a month ago and nothing has happened since. They have only just sent the kitchen appliance people back to fix up the rangehood piping. Its the builders who are slack in contacting their subcontractors. We are still also waiting on our kitchen window to be replaced to glazed window instead of clear to satisfy the occupation certificate. This issue was first raised in Feb! A couple of other fairly minor issues that we can live with or fix ourselves but its like they have disappeared off into the sunset since handover!
