Irritating promotional SMS's

<p>I have three contracts that I upgraded more than two months ago. I still get SMS's that I'm eligible for an upgrade and new handset.</p> <p>I phoned them on the 1st October to stop the SMS's. I was told that it was stopped. I still received the SMS's. I phoned them again and then I was told that they can't stop the SMS's and that I have to call upgrades or log a ticket that will take 72 hours before it will be actioned. I logged the ticket (Ref ********** ) and they said that I will get a message with the action taken. It is now two weeks later. I have not received a message from them, and I still get the promotional SMS's.</p>
