I didn't answer this call because I don't answer calls I don't recognize.. But it looked suspicious so I looked it up and saw these messages.. I'll report it too. Really, who has a last 4 digit number of 9999.
Recently started getting calls from this number several times a week. Caller's connection is usually very garbled as is the voice on the other end when there is one. They seem to very interested in your credit cards and in trying to get you to give them personal information. Finally I put the number in my phone's call blocker.
