Make sure you have a fake property in mind that recently went up in category from 4 to 5 and be prepared to create a reservation there and attach if necessary to get a conversion. You may need to get a supervisor involved. In my past dealings with them many times the agent took the hard line and was at first unwilling to help but framing the problem in a way that makes it their fault and escalating to a supervisor has improved my results in those situations.
