Got a call from them and didn't answer. I always Google any number I am not familiar with. Once I find out who this number belongs to i immediately block them from my phone. Sometimes I have to block them multiple times because they somehow find a way to bypass it. After that I no longer receive their calls. So much for the Do Not Call List.
Just got a phone call from this number and didn't answer it. They didn't leave a voicemail so I looked up the number online and found this site. I'm very glad I didn't call back since apparently it was a scam call. I usually don't call back if they don't leave a message anyways.
