Part of the spam club

I get spammed on my cell number by Hollard, I have asked them several times to stop, and no success. What these guys refuse to understand is I refuse blatantly to do business with companies that spam me. I just won't not even if they have the best product on the market. ie I am Gatvol for spam in my e-mail, sms's etc. I don't know where they have ****** my contact info, as I have never given it to them. I also always make sure the send me product info is unchecked on all forms / web pages.
