How come we can a man to the moon and we can NOT eliminate these calls?  I didn't recognize number, did not answer and they left no message.  Number is now blocked.  They call at the most rude time - meal time.

Call my cell phone, I did not answer, and no message was left.

Just received call from 312-340-0577 on cell phone, did not answer did not leave message will block
