I remember some years ago i would get spam calls from local area numbers, but the crazy thing is when i called the number back the person told me they never tried calling, the telemarketing was somehow being able to trick my phone into thinking it was a local number. Now i get telemarketing for my business, i never answer if they are legit they will leave a message. It doesn't matter if you block that number they will just keep calling from a different number, i do notice that some businesses have a prompt you need to listen to before you can actually talk to the business. I wonder if cell phone providers have that option?
