Called. Left no message.

No message left; caller blocked.

I probably had removed this number from my blocked caller list and got another call tonight; blocked again.

Calls at least 3 times a day - even  weekends.  Never leaves a message.

Constant calls evenings and weekends.  We have called the number back and told them to quit calling and take us off their calling list.  The guy just laughs and keeps calling, calling.  I have reported to the Do Not call registry, but I doubt it will help
