Scammer called my mother's number twice demanding her to call back so I did call back through her number. I knew it was scam before I called them and look this number up here first. I wanted to play games with them, after 2 minutes they hung up and block my mother's number. So I called them from my number and played games with them as well. The person on other line got furious with me and hung up, look like they won't be bothering us!
