cash crusaders shocking service failure

I purchased a brand new Doogee cellphone from cash crusaders around august 2019 in observatory Cape Town. I relocated to durban in september 2019. the phone just shutdown on me whilst in durban few days ago. as the phone is still under warranty i contacted cash crusaders local to arrange to bring it in and got shock of my life when i was informed that i need go to cash crusaders where i bought it which is in cape town. The warranty policy on cash crusaders website does not mention that, this doogee is even their brand and it was purchased new. I regret not listening when i was warned against purchasing this brand.
