this number just called me , google it found this . they called hung up right away i called back no answer it said to put a 1 before the number

The person called once and asked to speak to Mr. Or Mrs. My last name. I said he had reached the number and it was Ms. speaking. He panicked and then stayed silent. Then he pressed a button. When i said "Hello?" He hung up abruptly. Not fifteen minutes later he called back and as soon as I answered he said "Oh, ah--" and sprouted a bunch of jibberish. He proceeded to call back three times afetrwards, hanging up each time.
