Progress payment delayed due to mismanagement

DAY 1: After first progress payment inspection we were told 5 days for payment to be made for builder. They had informed us that our certificates expired - which we then faxed through the same day. After a follow up call we were told no fax was received - another fax sent and an email copy just in case. <br> <br> Every day we called the call center to track the progress just in case we were missing another document.<br> <br> DAY 5: we were told payment was not made due to a system problem on their side and that payment would be made before close of business. Just before midday i called again to make sure everything was ok, i was told they still don't have my initial certificate - after confirming they had received it two days prior. Then it was escalated (four times) i would be cc'd in all mail correspondence (still awaiting that mail) now before close of business i call to hear the update only to be told the document was never logged hence no payment. Now they have supposedly logged all the details and will escalate it. <br> <br> I now have to wait 5 days for payment as this will only be logged tomorrow.<br> <br> Not one single person has even called me back to explain, this is actually not ok
