don't know anything except they called my number left no message, I have never seen this number before and when I returned the call to find out , it says "number is no-longer in service"..might be private detective investigating an ex husband of mine whose cheating on his current wife by calling me..the 1st wife..his current wife is #4
"number is no-longer in service" means that the number is spoofed https://en.wikipedia.org/wiki/Caller_ID_spoofing and the caller should be treated as hostile.
This number has been calling me for the past 6 months and I have no idea who or what it is. Never leaves a message. Calls random times during the day. Since I have never answered, now another strange number has been calling...very similar except it is 443-234-5678. Whomever it is needs to grow up and quit calling or leave a message cuz I am not ever going to answer until they do.
