Spam sms' being continuously received

<p>For quite a while now I have been receiving spam sms adverts from ADT. The last month or so it is practically every day. Some days I receive more than one. On Wednesday I decided enough is enough so I went onto their website and sent them a complaint wherein I requested that they remove my cell number from their spamming lists. I also informed them that I have never givem permission for or requested spam adverts. I received a response email on 8 June 2016 at 1737 thanking me for my email and that someone would contact and respond to me within 24 hours. Well it is almost 48 hours and I have received no further response from them. Typical response / lack of response from South African companies.</p>
