Caller ID was the same as number did not answer. No voicemail was left.

I have got 10 phone calls from this number and it is very annoying. I don´t know what is the motivation of these calls but I want to let you know. They called a collague of mine as well.
Please, do something about it.
Many thanks.
Best Regards,

Manuel Matas

I'll get right to it after the football games. Unfortunately, nobody on here can do more about it than you can. This site doesn't offer call blocking and nobody on it can stop the calls for anyone but themselves. You don't have to answer in any way, and either a call blocker/app, or making sure they get a ringing phone only is maybe the best defense.
