Yes I got a call from 3862568738 . And decided to check it out . So it seems its a telemarkter. Well block it on your phone. If you can not. Then make them a DNA caller in your contacts. DO NOT ANSWER! You can do it to any number that you can not otherwise Block.
I get the same call several times a day. After the first time answering hoping it was an employment offer and nothing on the other end, I just look at the caller ID and DO NOT ANSWER.
