Samsung South Africa delivers NO SERVICE whatsoever

I have now at a point where I find Samsung South Africa's customer service absolutely abysmal. I have been on the phone with them since the middle of march to resolve a delivery that they were supposed to deliver as part of a deal with MTN. Nothing to this point. I have now been dealing with 5 people at their Call Centre etc. Their Call Centre agents whether it is the sales or the cellphone department just goes in circles by responding that they are waiting for the "Promotions Department" and will give feedback when they get it. Does no one pick up a phone to call someone anymore? How long does it take for someone to respond to an email? After this experience, as a loyal Samsung supporter with many items from Samsung, I can tell you that I will never again touch another Samsung product!
