What do I have to do to make you GO AWAY?

I have been receiving SMS advertising your service. I have on multiple occasions selected the OPT OUT option to stop receiving these pesky texts. I am further listed on the DMA OPT OUT DATABASE. The texts keep on coming. I have now started receiving telephone calls from a ****ing call centre. I have told the agent/s that I want nothing to do with your company and they must stop harasing me. Please stop sending me texts or calling me. As you can see I have chosen not to receive any communication from you. As part of my frustration I have tried to call you offices to tell you to leave me ALONE. Threre is no office number listed on your website. Only the ****ing call centre number. I wanted to send somebody senior an email, but there is only a sales email address. This is simple TAKE MY DETAILS OFF YOU DATABASE AND NEVER CONTACT ME AGAIN. DO NOT PASS MY DETAILS ON TO OTHER VULTURES WHO WILL BOTHER ME.
