Rental gone bad

This has been brought to the attention of a manager, LeRoy, however do want to warn other people. I viewed a property to rent on 8/3/16 and immediately advised Godfrey that we wanted it. He confirmed the place was still available and he would send through the forms to complete. It took until the evening of the 11/3/16 for him to send them through. With every call I confirmed with Godfrey that the property was still available. I sent the forms back to him on the 12th and again heard nothing. I called every day the next week -14th, 15, 16th, 17th each time confirming with him the place was still available and prepared to pay the deposit but he gave many excuses that he didn't have time to go through our application. At close of business on 17/3/16 I spoke to another person in the office as Godfrey was not in and was advised that the property had been rented out the week before. As i was assured the property was available I stopped looking elsewhere. I am moving out of my property which has been sold on 31/3/16 with nowhere to move to whilst our new house is busy being built. It's unacceptable but due to a shortage of rentals, all I can get is an apology with no solution.
