No after sales customer service.
I contacted them because the product that I bought from them did not work properly. So I bought a tablet from them and I set up facial recognition and pattern password. It was great but then suddenly the security changed to facial recognition and an actual password that I did not set up. It then asked me a password that I did not set up and obviously don't know the password. It completely locked me out. I contacted them about the issue and never received a response.
