Keeps calling. I tell and write messages to quit calling. Has not stopped

Stop calling please

is it a spanish speaking male? he won't stop calling me either.

This number  keeps calling me with some male talking about some pizza.

This number calls me all the time- morning through night.
Left me voicemails of laughing, singing, etc
A woman and a man are the prankers.
How do I stop them from calling me if I blocked them??
