Dreadful, Shocking service from MTN

My business upgrade is a total disaster and nightmare. I have done the application online, because according to them it is easier. The application took days to end in a contract (remember this is a upgrade, not a new contract). I upgraded to a Samsung phone with FREE EARBUDS. It was a special for August. The contract was signed on 26/08/2020. Delivery on 2020/09/03. No earbuds: I have to claim it from Samsung! Next, the camera of the phone is not working, just a black screen. Take it to MTN Centurion and they say it wasn't bought in their store, I must sort it out with Samsung in Menlyn! A very unhelpful and clearly irritated consultant helped me, and was way more interested in his own cellphone, than to assist me. I had to phone the MTN consultant who was assisting with the deal originally from my cell phone. On MY airtime, he pas put on hold. I asked him if he can please phone them back as my airtime is running out. Nonchalant the answer came " With what?" I asked to speak to the manager, which until now didn't pitch. In the meantime his lunch or food is delivered. He simply walked out of the sore and left me there. I just could not believe what just happened. Unfortunately I now sit with a contract with them, but I am utterly disappointed. Be WARNED: don't upgrade online, you have no support if anything goes wrong. I now have to wait two weeks for them to sort it out. I now have a contract but no phone, they have taken it in to send to I don't know who? THIS IS MTN! I tried to phone the store SIX times to sort the incident out with the manager, but they don't answer the phone. Being in the store twice today, I am not surprised, they have no idea how to work with customers and no pride in their work.
