MTN Summer Remake Spam

I use MTN via Afrihost. I diligently unsubscribe from all of MTN correspondence. Recentley i have been getting marketing messages from MTN for Summer Remake 2020 promo. 1. You can not directly opt-out from the message itself. 2. You are forced to dial *135# 3. There is no option to opt-out!!! 4. You are given no instruction where to opt out. There is a choice of six menu options, and none are for opting out. I am registered as a no contact with the DMASA whom MTN is a member. Since day one using MTN i have used all options to unsubscribe or remove me from been contacted for marketing, yet you still ignore my request and periodically still send me your garbage marketing. If i am not completely removed from any future communication i will be taking this further with DMASA / WASPA and POPIA if needs be. I am fed up with this constant fight with MTN.
