These [expletive deleteds] are getting sneaky! Their phone number did not show up on my caller ID for me to enter it into my call blocker machine. Fortunately their phone number WAS recorded by my call blocking machine so alls I had to do was to press the red Blacklist button to permanently block future incoming calls using that number. But once I did get their number from my blocking machine, I called them back and unloaded on them. Hard! F those f'ing f'ers!
