They have been calling daily.  This phone number is blocked on my end.  However, being curious, I did return the call. He speaks only Spanish, in a low voice, from the very beginning The first time I hung up.  But today,  I told he to speak English, but, he just rambled on in Spanish.  I told  him I did not speak Spanish and did not understand him.  He hung up.   Hopefully, he stops calling. If not, I do not care as the number is blocked and I do not hear the first ring (feature in my phone).
