I get these calls constantly. I have allot of the numbers saved in my phone. When they call, I just answer the phone and dont say anything. They hang up after a few hello! hello! 's go unanswered.
Sometimes, I will say something broke up like hello....... can you hear me? hello hello. It is funny messing with them.
I do that often.
If they waste their time with me, thats less time to scam someone else.
I just received this call about 2 minutes ago.. they left a message which my voice mail identified as 'SURVEY'. The message the left said something about lowing interest rates... i don't have credit cards or a home in my name so yeah...straight up SCAM !!
