Received an call from them Redialing brings me to "a number who is disconnected". When answered on the second ring the caller showed with no answer so I assume that it was a hang up with multiple dialing and just talking to the first answered.
Got a call. Didn't know who they were and didn't answer. They didn't leave a voicemail. Same prefix as other calls I've received but the last 4 numbers change.
This number just called 3 minutes ago. You call it back and it says the number is disconnected. The same number (minus the last 4 digits) calls almost daily. I now have about 8 numbers blocked from here.
