Pathetic Service from Blackview South Africa

Blackview South Africa has the worst service ever! I asked them to fix my screen on a BL6000pro and then I got told that my charging port and back cover must also get changed when the items still work. They refused to just repair the screen on the BL6000pro. When I went to collect the phone that was not repaired, my friend asked to speak to the technician, due to the guy who helped us answering every question with the phrase "I'm not a technician so I can't answer that" . The technician refused to come and talk to us.
