Caller asked to be transferred to a name given to me.  After a few seconds of having trouble finding the person he then asked if he can be transferred to someone who is in charge of a magazine subscription or a office manager.  They are trying to get updated info on our company to get subscription we have with them.  

Purports to be calling from Offshore Engineer magazine.  Have been calling frequently despite being told NOT to ever call our number again, that we do not want the magazine.  I have threatened to report them but not sure where to go.  They will not stop calling, asking for different first names in an attempt to talk to someone and send a subscription

This number calls my office several times a day and hangs up.

Caller hanged up on me as well. No word heard from the other line. Could be a deaf and mute? LOL
