Pathetic start

I have recently taken up a contract with mtn. And from the start its been a mess. The sim wasn't rica'd initially. Even after going back to sort it out it wasn't corrected it took a second visit where I also asked for unrestricted apn access and was told to call for it. After calling 135 I was told it will be sorted out. I did this and switched off my cell for 15min. Ill have to phone again even though their calls are recorded. Cause I garantee if they can do a basic request why will they go and list to a recording for 26/03/2023 to correct this? I still dont have unrestricted apn access! I took the sim for the sole reason so I can remote log into another divice for one hour a day eg. Remote play , remote vnc. I dont have time to call for this again. I will be contacting icasa and national consumer act as I have a 2 year contract that serves no purpose!!!! ***
