Recieved several calls from PCA Security claiming to be a security company and that they could only talk to the owner.  I asked them to remove our number from the lists and they would not, saying that they'll just call back until they reach the owner.  I read the posts, saw the one that said the company wouldn't remove the numbers.  I decided to call to see what would happen. As things would have it, Michael Brown got on the phone after a 10 minute wait and told me to use his name as all of their offices are well aware of who he is and that they might by chance call due to a doubling up of the main company number.  I'm to tell them that Michael said not to call and they will stop.  Hope this helps.

Company is PCA Security - real # is 866-593-7157. Kelly from Telemarketing in Michigan called our office and advised the office manager that she would continue to call until owner was spoken to. We are a Corporation, no "owner" available. Ever. I called the PCA Security company and was told that we would NOT be taken off the list, she was doing her job. They must be Scammers to be that desperate.

Calls from several #s come up with the name SEC. I have 3 office #s into my phone, and all 3 get calls from these guys. They ask for the business owner, then won't leave a message when I say they're unavailable. I get at least 3 calls a day.
Once, when I told the person they had tried before, they said, "I'm the only person who sits at this desk and calls from this number." When I told them that I saw their company name on my caller ID, they didn't have a reply & hung up.

Person called asking for business owner.  when i informed her that they were not here, she hung up.  about 3 hrs later someone else called and asked for the business owner.  I asked who was calling and she said pca security. i said no owners are ever here and she hung up.  they keep calling
