Mar 16: Answering machine spam: Recording of Michelle with mortgage services

This recording has called Mar 16. An almost identical recording of Tim with mortgage services called Mar 13.

"Hi this is Michelle with mortgage services. I'm calling regarding your current mortgage. I want to let you know that I have a lender who wants to preapprove you at one and a half percent on a thirty year loan. Whether you're looking refinance or take cash out this loan would save you hundreds of dollars on your monthly house payment. So please press one NOW to speak to a loan specialist and start saving money NOW. Once again, press one NOW to speak to a loan specialist. Or press three to be removed from our marketing database. Thanks and have a nice day."

Pretty much identical except for minor changes in wording:
"Hi there, this is Tim with mortgage services? I'm calling regarding your current mortgage? And I want to let you know that I have a lender who wants to approve you at 1.5% on a thirty year loan now whether you are looking refinance OR take cash out this loan would OBviously save you hundreds of dollars on your monthly house payment. So please press one NOW to speak to a loan specialist. Once again, please press one NOW to speak to a loan specialist. And start saving money NOW. If you would like to be removed from our marketing database, press three. Thanks and have a great day."

Obviously the same script, just different voices. What's the point of that? So that they can claim that someone removed from Tim's marketing database wasn't removed from Michelle's marketing database and vice versa?
