Who called from 6303263334

This is a call from a cruise ship line asking if I could hear them ok.  Saw on news that if you say yes you will get charged for something.  Think this could be a dangerous call.

Calls few times a week.  Says this call is recorded - can you hear me.  Saw on the news not to answer & blocking the call isn't working.

I don't answer calls from unknown numbers, under the assumption that if it is a legitimate caller, they'll leave a message.

This caller left no message, and hence didn't meet the criteria for a returned call.

Typical scumbag phone-tag

Called # back and got fast busy.  BLOCKED'

Numerous calls. Never leaves a message. BLOCKED.
