Have received numerous phone calls from this number. They do not say anything when i answer and they never leave a msg when i ignore.

Same here.

same as the rest, I answered once and did not say anything. you will hear a robot listening for a "Hello?" as to start a pre recorded message.

Called left no message.   Tired of this number calling me.  I have put on reject list, but still.  I though solicitation calls were not aloud on cell phones.

Call numerous times, never left a message,  and when I answer,  they hang up. Got a missed call today, I returned the call. For a cruise line, in mid sentence of telling them to remove me from the call list, she hung up on me. Hopefully this stops.
