Dec 18: Recording of fraud by "Dorothy" with the "mortgage branch"

This recording has called at work on Dec 8 and Dec 18.

"Hey guys, this is Dorothy with the mortgage branch. Um. Just wanted to give you a call and let you know that your home and your area has been approved for our new one percent refinance program. Now, this is something that's good for only the next seven days. So if you'd like some additional information on this program, go ahead and press one on your phone right now. This one percent refinance program is something that you could use to pay off some bills, take cash out of your property, or just take a vacation. Once again, if you'd like additional information about this program, simply press one on your telephone right now. Thank you. And have a great day."

What happened to the seven day limit that started Dec 8?
