ID says that the call is from "David Carr" but we don't know anyone by that name. When we answer a sweet sounding young lady is there and tells us that she is with "the rewards center" and is calling because her records show that we've recently stayed with them. It's at this point that I usually hang up. These people call using that same lame intro many times throughout a month with different phone numbers showing up on the caller ID so I'm fairly certain that they're spoofing the numbers. I just keep adding them to the blocked list but my blocking device only holds 2000 numbers so I wonder how long it will be before it is full... Not long at this rate.
