Bad service and customer relations of Oukitel SA.

I bought an Oukitel WP18 Pro cellphone from Takealot in late May. I took it to our local Chatz store for a simswap to nano sim size. I had the phone in my back pocket. When I got home I took it out of my pocket and noticed the small glass panel around the camera lenses was cracked and that section was very hot. I contacted Oukitel SA and attached a photo. They offered to pick the phone to repair the phone but not under guarantee because I abused the phone. I said this happened before a single phonecall was made. I got nowhere with them so I contacted Takealot and they picked up the phone. I insisted the phone to be replaced. They also said I abused the phone and sent it back to me unnrepaired. I still insist that the phone be repaired free of charge. I think Oukitel SA has no consideration for their customers and do not have the slightest skills to work with customers. I also got no explanation why it get so extremely hot in the area of the cracks. Their service stink Kobus Bender.
