Called several times including after 10 pm

This number has been calling my house for days. I do not answer callers I do not know. My answering machine answers with the following message: "We do not take calls from telemarketers. If this if family or friends calling from a number we do not recognize, please leave a message after the tone and we will get with you as soon as we can.:"

This caller has never left a message. Apparently the caller got upset about my answering machine message and called 10 times yesterday, especially last night a few minutes between each call. The night before, the caller called many times during the day and then a call just before 9 p.m., plus two more calls after 9p.m.

no message

Called a couple minutes ago - ignoring these calls never stops 'em, but call blockers (like mine that simply pick-up then hang-up) certainly reduce the overall number of calls. This one is brand-new to me, but based on the lack of name, no voicemail and reports here, it's getting blocked.

Call no answer.
