Yep, I agree. Called on my cell and left no message. Block and delete as usual. This seems to be a daily thing from all different numbers. No one is doing anything about these stupid calls so the best thing to do is not answer them and block and delete them!
Didn't leave a message. Came over as wireless caller. Two minutes before I had a call listed as private caller. An hour before that a call came over as unknown caller. Ho-Hum.
