Steve Michaels with National Diamond requesting to speak with the owner of my company by name. Spoke with the owner, he didn't know who he was. Steve was very rude, when I asked what he was calling about he said 'just put me through, he knows exactly who I am'. When the owner refused the call and I asked Steve if he'd like to leave a VM, he said he'd just call him on his cell phone and hung up. Caller sounded foreign.
