NO ANSWERS FROM CHUWI TO FIX A PROBLEM

My Time here is to fix YOUR FAULTS!! YOU SEND A WRONG FIRMWARE. I spent week over week to fix YOUR PROBLEMS: SEND THE RED BUTTON FIRMWARE FROM a Hi9 Plus Tablet Android 8.0 with RED BUTTON - QUICKLY - it is new and look my reports for the problem I wrote to you any times, with no answers and and wrong firmware. The result is a splitted Screen/Display. There are also more than 3 people with same problem. AND YOU DO NOTHING FOR YOUR CUSTOMERS!!!
