Who called from 3132215101

Unknown number.

No message.

Received this call at work.  Answered and nobody spoke.  Disconnected the call.  No doubt it's a scammer.  They always always calling me.

The call me all day and never say anything I've blocked them but they still call somehow

This number calls my work phone all the time along with another 313 number. There is always dead air on the other end.  Its quite annoying. I am not sure what the purpose of them calling me is.
