Something similar has happened to me. I have sent an email to that same address explaining my case, I have not received any response.
I have also sent it to the administrator of this forum by PM, and I have not received a response either.
Very happy with the service they gave me with my BV6000 but the Blackview of 2016 was much better than the Blackview of 2019.
My current BV9600Pro, it broke the LCD without me doing anything, and I had to pay for the repair. They told me that as I had exterior blows that the warranty did not cover.
What do we do? Why do we buy phones that can withstand bumps and falls? To leave them inside the box? Do they want us to buy a phone that can withstand extreme conditions and then we can not use it so that the guarantee can cover its failures? It is a shame.
I bought 2 tempered glasses sold by them on Aliexpress, and neither of them beat well. I bought another two from another seller, and the first and well they stuck on the phone screen. They will think that I do not know how to place a tempered glass ...
I bought a W1 wireless charger on Aliexpress and on the third night, on the third use, it burned. Literally, it burned. There they sent me another one, but I bought it in gray because my BV9600Pro is gray and the one they sent me again, they sent it black ... but at least they sent it.
Now my phone's speaker sounds bad. If they call me, the ring tone sounds and after 3 seconds or so, the sound dims, then increases, then dims again and so on all the time. The same thing happens to me with YouTube, with music, with any application that has audio.
Also, I had to pay for the loudspeaker to be replaced because it had metal shavings and that was not covered by the warranty either. Then you see videos of how they weld with him, how they cut with him ... we go trick advertising.
Blackview are you laughing at us?
