Not getting answers

We are trying to get money released to pay a house. Money was paid into the account Saturday. When we tried to do the payment for the house we were told to wait as they needed authorization. After a long wait we were told it would be released today and they would call us. Today we called them, only to be told 3 working days. We are not getting real answers and we need to do the payment by today or we risk loosing the sale.
