Worst repair I've ever experienced, sent it for repairs after a month finally got a response from them they repaired it but were unable to do diagnostics so I was told it will be under manufacturers warranty to replace the motherboard which I agreed now they telling me I owe 1000 in repairs when it 267 rand what's the point of having insurance with Vodacom if they don't cover a phone that would cost just double that to replace
