NO SUPPORT FROM XIAOMI's "OFFICIAL DISTRIBUTOR"

I purchased a XIAOMI Mi TV stick off Takealot in March 2021. 3 weeks ago, when I switched the device on to watch Netflix, it displayed a request to authorise an update - which I did. The next night I was watching Netflix when the device simply switched off (no load shedding). It looked like it would start loading again, but instead it now cannot get past the black screen with the grey mi brand in the middle. I am unable to hard reset the device according to the advice I could find online. It is completely unresponsive. The device has been bricked by an UPDATE!

I cannot log a return with Takealot, because the device is now out of the warranty. They refuse to help. Xiaomi global support directs me to the retailer I bought from (Takealot) who refuses to help. Mobile in Africa (MIA) who is apparently THE "official distributor" of XIAOMI in SA refuses to help! If not they, then who??? This was an expensive purchase that is now a useless piece of plastic after an unreasonably short period of time!! DO NOT BUY THIS BRAND! THERE IS NO SUPPORT IN SOUTH AFRICA
