Unwanted messages

<p>To whom it may concern</p> <p> </p> <p>I previously app**** for a spar card (discount card) and added my phone number there, I went to the branch in Midrand and I was informed that it was impossible for them to remove my number, I have to live with the sms. I dont understand how they could develop a system where a preson cant update or remove his details on their system.</p> <p> </p>
