Just had a call from this number minutes ago. No one at the other end and they hung up after 30 seconds. BTW I am in the 770 area code so I thought this was a local call.
When called back, there is a recording where they claim to be an independent survey organization. That's pure BS, as such organizations cannot call numbers on the Do Not Call list.
Getting quite a few calls from, 770-679-8415, 770-773-7200 and 770-872-4378. When I search the numbers the reports say the caller ID comes up as SSI. I'm assuming this SSI spammer has quite a few phone numbers. I don't answer the calls, I just block them as they come in. I don't bother calling the number back.
