Definitely the same group. Corporate Acquisitions from Colorado. They use GotVMail.com which provides local numbers around the country. Makes them look like they are from Western Mass. Call the number and you will get a voice message and a long list of voice mail boxes for all the people at Corporate Acquisitions.
Thanks for the comments.. I own a small company in Memphis, Tn and received the same call this evening. He left the same recording message. What a scam....
