I didn't answer. No voicemail.

Unfamiliar caller number. I didn't answer. Caller left long (2 minute) empty, silent voice mail.

Just received a call from this number from someone who asked if I remember filling out a coupon for a trip with my phone number (this is my work phone so I do not give this number out to anyone). I told him no and he said yes you did. I asked him to prove that I did by giving me the name on the coupon, to which he said "that is not relevant now you filled out a coupon" I kept asking him what was the name on the coupon I filled out and he continued to ask me something which I did not understand. Then I started just saying Scammer, Scammer constantly.. finally I hung up
