This caller left no message and anyone who calls me has my permission and always leave messages. So this must be a spam caller not wanting me to know there information. How can you respond when you're unavailable if no return information. Please have these callers stop calling me if they don't care to leave a message.
Nobody on here can physically stop anyone from calling anyone, the site doesn't offer call blocking. What we can do is suggest how YOU can stop them. Many suggest a call blocker, or blocking app. Another way to stop them if you're able is to completely ignore the call. No message will be left since it's unlikely the caller is prepared for an automatic answer. They're after a live voice most, but any kind of answer still gives them something.
