STOP CALLING ME!!!!!!

I am not sure if you employ a bunch of THICK IN THE HEAD people. Maybe they cannot read or maybe they are all deaf!! Every SUNDAY I get 2 to 3 calls from Phonechoice trying to sell something to me. I keep telling them I will order online if I want something but they keep calling! I cannot remove my number from their system and they do not understand me when I say STOP CALLING ME!!! ***???? Someone needs to do something or I will have to start using the WHISTLE METHOD. Every time they call me I will blow a whislte in their ear as loud as I can. Lets see if they understand me then?? LEAVE ME THE F@##&CK ALONE. As soon as my account os paid I will not shop with you again. That you have in writing now.
