E-Great already knows what part I need and refuses to send it to me, they need me to send my device to China (and afford it) so they can fix it and send me back. In the begining, they informed me that they would send me the part, but in the end they just said that only changing the part could not repair my device.
KJ Global told me that they could only send me the part once China send it to them first.
In the end of the day, my device is not working and the only option I have is sending it to China, wich will be very expensive and without the guarantee that I will have the device back or keep with it here broken as it is now.
