FNB Connect/Device Guru/Digital Planet

I bought an Iphone via the FNB Connect in September 2022, after just using it for a weeks I realized that the device keeps switching on and off, contacted FNB connect via Digital Connect or Device Guru and they took in the device and was replaced with another device. I was not told if the replacement device was new, user or old but I doubt if it is a new device. After receiving the replacement device, I realized that the front selfie camera was not, tried to trouble shoot using youtube videos but to no success, contacted Fnb connect, they collected the device and took almost two weeks to give me feedback. The device was returned with a repair slip indicating that the front camera was replaced. Upon receiving the device, I tested it, and still the problem was not sorted after the technicians reported it fixed. Reported this again to Digital planet/device guru, took more than 48hrs to respond to me, after that I get a response that was written on the replacement slip that the camera was replaced. No feedback is given, everything is done at a snails pace, no urgency. How do you return a device without testing it if the matter was resolved? And the consultants do not take ownership and responsibility of the lack of proper service, follow up commitments are nor honoured, it very frustrating. Have been using fnb for all my life but I’m really disappointed at this utter poor service. On both these devices I have bought accessories, screen protector and covers and all these things I have lost money up to a value of just over R1000 and even now I don’t have a phone, let alone when the device is being attended to
