You can file a complaint with the FTC (Federal Trade Commission) by going to the Federal Government website at "www.donotcall.gov". Just click on the green "submit a claim" button. Please note, for the case of recorded messages you do not have to be registered on the Do Not Call List in order to file a complaint. Also, an individual complaint will not be investigated by the FTC. However, if many of the people seeing my message follow through and register a complaint, the chances of an investigation will increase. The complain process should take no more than 1-3 minutes to fill out the complaint form.
Called at 5 AM EST, with an ID of Phoenix, AZ, but luckily my cell phone was on do-not-disturb, so only saw it later. They left no message. Called back to get the number has been disconnected message.
Called at 12:57 am. When I answered, a message immediately stated "your request to be removed from the call list will be fulfilled immediately." Scared me to death. Tried to call the # this morning - no longer in service.
