Do not know who this is and did not leave a message.

They just called me from this number - a mysterious company called "warranty help desk" telling you your car warranty expired. They didn't even know what vehicle I owned so they are basically spamming people.

Company called "warranty help desk". I have been getting messages on my cellphone saying the warranty on my car has expired and needs to be reactivated immediately. Finally I picked up and got these people on the phone. I asked what vehicle they were calling about and they said they don't have that information, that it would be any vehicle I own between 1999-2007. Obviously spammers.

They called the cell phone >:[.  Not wasting daytime minutes for an unknown.  Unfortunately, cell phones only display the number.  Would love to get a name too.

Earlier, house phone got a call from "Unknown Name, Unknown Number."  Been getting those everyday several times a day.  Don't answer those either.  Tried the call back feature and they have their number blocked.  To track that caller down "I" have to pay to put a trap on my phone.  So the victim continues to pay to be victimized.

Today when that "Unknown Name, Unknown Number" called again I picked up the phone and didn't say anything and the house was quiet.  Eventually a man said "hello? hello?" a few times before he finally gave up and hung up.  Hopefully that'll be the last call from "Unknown Name, Unknown Number."

I too got a call today, my cell phone ID'd the number, but caller left no message.  I'm with you, not wasting daytime minutes for an unknown, especially one who won't leave a message.
