Got a call but no message left.

i believe it's a computerized call offering a discounted cruise since "I was a former client."  Never been on a cruise.  The message might throw you off a little since the "person calling" hesitates while saying they had problems adjusting their headset.  Then the "person calling" goes on an unrelenting sales pitch in which, once you attempt to interrupt, you realize it's a recording/ computerized message.  I blocked this number this weel but received another call today

They called my cell from 312-800-0251. I did not answer, because it is not a number that I know. They did not leave a massage.

I get call from person who represent himself as police representative and request if I support the police

called me then said no one was available to take my call. No company name
