Caller ID " Miami, FL." I don't even live in Florida. I was getting calls from 472-260-5513. Clearly they don't check these sites.

They call me at random times. I pick it up, and they hang up. If I don't pick it up, they leave a voicemail of silence. I try to call back the number but it says my call cannot be completed as dialed. I googled the number and landed here.

Caller ID said it WIRELESS CALLER. It was some guy with a strong accent saying he was calling "about my credit card." I know better because I don't have any credit cards. I hung up on him after that.

They have called me over and over from a few different numbers and I know it can't be one and when I pick up they hang up. They are so desperate to get money from someone that isnt on the phone that they do this and will do anything to get it from people that don't have it so you can get to them. So what do you do? They cant call you until your number is removed . It would cost them money to call me and answer but when they call another time and

Call back number given is 855-218-8970 and that's not even a valid callback phone number. I think if you're trying to scam someone there's no need to call back a number to try to confirm your identity.

Just got a call from this number and also received the same text (thanks for the update! )

Report for 1-5102347887 - 2018-11-24
Got the same call, it was strange and was about the same time frame as others. It is very important to return this call. The person said that they tried to serve me but they did not have any documents with my signature on it, and they had a file in California, and they left out of state numbers. Just another scam...
