573-722-2023 = caller id = 573-722-2023 = keeps calling never leaves a message, long pause is you do pick up, uh oh, clear sign of telemarketer...spammer....for sure...I am blocking and so should you!
It is a Telemarketer Scam Caller or a person that has a bored and a lot of times on the hands all day, no matter how many numbers you block they will call you back with different numbers as they are spoofing numbers and no way you will track them down,
They call from all over and using phony phone numbers, if you do talk to someone DO NOT GIVE Them any personal information.
