Some suggestions:
1. If you have a Homeowner’s insurance policy, check to see if it has Identity Theft coverage. If so, follow the requirements to take full advantage of it.
2. Some posters have suggested that the call itself a phishing scam. Seems likely (why would the thief supply your current phone number?).
3. If you are convinced it was genuine, get the name of the top official or general counsel of the Dept of Children & Families. Send that person a demand by certified letter, replete with facts, names, times, and dates, that they take action on this immediately. Demand a response within x days stating what action they have taken. Demand to know their policies about reporting id theft, the number of reports in the last year, and the number of cases that resulted in prosecution.
4. If they do not start dealing with it immediately, write letters to the editor of the local newspapers, warning the public of this id fraud danger. Revealing the lack of action by the agency, and imply that you are beginning to wonder of if the agency condones and abets id fraud.
5. One would assume an application to receive food stamps, would involve some sort of physical contact, a phone number for future contact, and an address or account number. All the agency has to do is ask the applicant in for an appointment to get their hand-out card, then slap on the cuffs. Their failure to do this already tells you they have no desire to catch the scum.
Google search the number they are calling from - Others may have already reported it.
Google search the name of the person you are in contact with.
Google Search a specific, pertinent and convincing statement the person made to you.
I thwarted a “Toner Scam/Office Supplies” and a “Safety Equipment” scam this way. I thwarted an identity theft scam when my “Insurance Company” called to verify “updated driving records and mileage”. The caller needed to verify the current mileage on my truck to verify if I was driving the amount that I had originally stated years prior. They also wanted to update my beneficiaries for my life insurance policy. They knew my insurance company and the name of my agents as well as some specifics about my policies. They said they were calling from “corporate” when I asked to speak to either “Joe” or “Jane”, my agent or his assistant. I told them I would go check the mileage and instead, while they waited, I checked google and found exactly what the scam was. When I started asking questions of her to help build a case, she caught on that I was doing the fishing and hung up. I still have the recording I started somewhere on one of those little cassettes. I reported it to several groups including my insurance company and never heard back from anyone.
