Actually, most here on TUG would recommend that you not call any department at Wyndham while your rescission request is still in progress. Wyndham is under no obligation to update you on your rescission or refund status. All that Wyndham is required to do is process your rescission and issue you your refund within 45 days.
Refunds usually do not take that long but phoning the departments will likely accomplish nothing for you except for them to try to convince you to reverse your decision to rescind. Besides, the method that is usually legally binding is the certified letter and not a phone call.
Wow good to know. I was thinking there would be some way to check on the status. I guess not if we are working with a company who's entire business model is to shower people in gifts when they sign up until five days are up and we realize we are screwed. Still if they are that shady I still could see them saying "I dont care what USPS says we dont have it and you are paying."
