Who called from 5672444026

I'm in Canada and i have no idea why someone would phone me from Ohio and not say anything. Its  starting to happen to often that i get calls of this type. I'm now trying to track down the offenders when i can. This is the second call of this type today. The 1st one was from Bolton, Ontario, Canada

I have had several calls from this number over the last couple of months. They never leave a message.

I received a call from this number today.  I told them I'm on the do not call list and they hung up.

Rang landline, Left no message.

They call us upwards of 10 times a day. Sometimes there is a person on the line others it's dead.
Also in Canada. The display name comes up as LCL.
