Clicks keeps sending me Spam Emails and won't remove me from their email lists after unsubscribing every month!

<p>Since April 1, 2016, I have been receiving 1 email for each month afterwards from <span style="background-color: #ffffff; color: #757575; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 13px; white-space: nowrap;">clubcardcommunications@</span><span class="lG" style="background-color: rgba(251, 246, 167, 0.498039); outline: transparent dashed 1px; color: #757575; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 13px; white-space: nowrap;">clicks</span><span style="background-color: #ffffff; color: #757575; font-family: 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 13px; white-space: nowrap;">.co.za. These emails offer personalised savings and are sales emails. I don't have a problem with that. What I do have a problem with is that every month, since receiving these emails, I unsubscribe from their lists and emails but then I still get those same emails every month any way. I have reported it as abuse to their customer care team and nothing, I have responded to the emails I get everymonth and I receive no feedback. These emails are SPAM and are Abusive and need to stop! </span></p>
