I too just got a call from this number and the guy said uh hi and then never said anything else. I tried to call it back and it rang a few times and then said the number was no longer in service...weird.
Brian Stevens who claims he spoke to me last week about lowering my credit card interest rates and making paying them off easier. Funny, because I have no balance on any credit cards and haven't used a credit card in 5 years. Clearly a scam. Don't feed into the BS.
I answered to someone saying "uh hi" then nothing for a few seconds before disconnecting. When I called back immediately afterwards I got a recording saying the number had been disconnected.
