This appears to be a spam caller of a fished #. When called back,  "this mailbox is full"  was on the recording

This is Jennifer Rajkumar who is running for office in New York City. She trespassed and snuck into our apartment building and went door to door and put flyers under doors. She is rude and obnoxious. And if you happen to answer the phone after she calls numerous times without leaving a message, the caller will rudely hang up on you. We are making a point of voting so that we can vote against her!!!!
