There is no real answer to this questions. Trouble Tickets stay activated for at least 90 days. However, hotel credits can sometimes take a month or more to come in because some of the hotels don't report but once a month and only allow trouble ticket submissions once a month. There is nothing else for you to do on your end. The administrators can see your TT on their end and will continue to try to get your credits. Sometimes they will come in after the 90 days. You may see the ticket closed at the 90 day mark but that doesn't mean that if the credit comes through you won't get it. As long as the merchant doesn't deny the credit outright they will continue to try to get credit for it. Hope that helps and good luck on your credit coming through!
