Tevo X100 S****** no spares

The charger on my son's Tevo X100 s****** stopped working. I went to Makro to get a new charger but it turns out that the stores only sell complete units and they cant help with spares. They gave me a number for Tevo in Centurion which I called but they don't have stock of chargers. This was in Mid November. Refilwe told me that they would receive stock on the 24th Nov 2017. This stock never arrived. I called today 18th Dec and now they tell me I have to wait until February 2018 to get a new charger. How can it take 4 months to get a charger? In the meantime my son must just look at his s****** while he is at home on December holidays. This is unacceptable service, how can a company like Tevo not keep spares for products they sell.
