Called and left no message I know no one in Plano Tx

Received a call from this number yesterday & they hung up. He called back again today and stayed on the line & asked for my boss.  I told the man that my boss wasn't available & he asked if he was on another call (pushy) I told him that my boss IS NOT in the office & he said he'd get him on his cell phone, yeah right. I asked who should I say was calling & he hung up on me. Psh.

A guy asked asked for a Martin. I told him there isn't a Martin who works here. There was no response, then I hear another guy in the background yelling repeatedly, "how many phone lines do you have?!" Shady.

Called our business a few times and each time there is a pause then someone says "nailed it". How the eff do we get this to stop? Our business receives 20+ telemarketer calls a day. I have better things to do than deal with this nonsense

Have been called multiple times from this number, and the person always asks for my boss.  I have been asked not to transfer calls until I know who is calling and what they need, to some extent.  When I asked this guy who he was and what the nature of the call was, he got extremely rude with me. He began demanding to talk to my boss and that I give him my name.  He refused over and over to tell me why he was calling.
