The calls are from Wyndham Vacation Resorts, Inc (Time share) telemarketers.
Call then at 800-251-8736 (owner reservation line) and use the menus to get a person and then asked to be put on the do not call list. they will also sent a confirmation letter if you ask that you can use if they keep calling in court. I am sure that there is a class action lawyer looking for this one.
