I keep getting calls from this unknown number & there is no one at the other end when I answer it.

I got a call from this number 3 times today, each time it was a hung up. I sent a txt asking "who is this?" I got this conformation message "your text was successfully delivered to 952-447-6064. How these 2 numbers are linked - I have no idea. All I know is I hate being harassed by such phone calls. Knock it off, whoever you are!
