someone wanting money and card number

These people are harrassing myself and the operator down stairs, they are yelling at her because she won't transfer the call to me.
They have called over 20 times in the last hour.
I sat with the operator and when they called i told them this is a place of business and i was calling the police.

Individual called 4 times now in the last 4 days, asking for a Heather Garett.  I have told him repeatedly  that no one with that name lives here.  I have been polite until this last time when he called me a liar.  HE will not give me his name or company he works for.  I told him he is talking to a military member living over seas, and he still insist that Heather lives here.

these people keep calling and saying i owe money and that legal action is being taken against me if i dont pay. I told them I contacted the FTC, FBI and the US Attorney Generals Office. Screamed at me that they would see me in court. The number keeps changing that they call from as well.
Said it was for a payday loan, and they were from a law firm National A? Processing Services. Couldnt understand the second word. Anyway, they wanted my card number for payment.

I just got a call from them today. I recognized the guysvoice right away, as they had been calling me from another phone number. They stopped for a few days after the state police called and told them not to contact me anymore. Today i told them there there was nobody here by that name, my name was maria and i didn't know who he was talking about. he seemed confused and hung up, but it's only a matter of time before they call me back. I wish we could get these people shut down!! They previously called me from was 851-322-8600.
