Update: Well I called today was offered a gold challenge for 6 nights told the rep that I would complete that by the end of next week. Told that a Plat challenge not available, as she could only upgrade me to that challenge based on I was already requested one the other day. Declined request told her I would just continue staying with my current hotel chain. Moral of the story, call and ask don't send an email as they record this information to your account. Also this was the supervisor on duty.
