Bad service

I did an upgrade with retentions department. Gugu helped me but she was shouting me when i explained to her that I dont like the device. I took the phone in 27 March 2023, the handset warehouse confirmed that the device was approved. I was than told to call support for device to cancel a week Mfundo Mthethwa called me we had a chat told me that he will call me Friday that 2weeks ago till date i have been waiting. Simple cancallations. My IRMS NO. ***. MTN is Kai
