SCAM. DO NOT ANSWER. They record your number as an answering number and then share it or sell it to other telemarketing companies. If you want to hold one of their lines, just answer and leave the phone down and come back later. But it is better to not answer and block it. No use on searching source because what you see is only a typed ID not the real source. SCAM SCAM SCAM!!!
So, for the 5th time today, I got a call that was AGAIN pre-approved for a $250K loan (even without never applying for one) and the only thing I need to do is to press 1 lol Uhnn... NO! Blocked!
