Poor, Pathetic and Rude Agents

I'm so disgusted with the MTN service i received from their 2 agents. The first agent whom i spoke to regarding a Sim network unlock pin said i can't have get i have to wait for 72 hour. I mean how pathetic can this be you purchase a device from MTN in 2021 and then 2 years later you are given a lame reason that a case needs to be logged for you in order to receive the unlock pin and you are in the middle of a crisis so from where the agents are sitting they are literally telling you to hell with the fact that you don't have a phone in your possession. And the second agent i Spoke to "CEDRIC NKOSI" who was speaking over me and even sighed at some stage and said ayi he sounded very irritated by me and eventually got a manager who then pretended he can't hear me!

How does Cedric Nkosi come and make comments regarding other service providers whereas he's working for MTN?

Also why must we continue buying MTN devices if later on we'll have problems with using other networks and the device is dual sim card!

The Service i received from @MTN South Africa is very poor to say the least.
