They won't say what their business is if they haven't called for you (who answered the phone). They simply say "it's a personal business matter" and will not leave a message.
I found this though: Cap Research Institute Inc.
14420 W Sylvanfield Dr
Houston, TX 77014

I believe they are actually doing business as Amidee Capitol LLC,, 14420 W Sylvanfield Dr # 100, Houston , TX 77014 - 1625. They claim to be a Real Estate investment firm, but why all the secrecy? 281-315-2100.

If you Google this phone number you get the United States Conference of Catholic Bishops?? If you're not Catholic, I have no idea why they would be calling you. Even Jehovah's Witnesses come in person.
