I bought a 8x honorary phone from the showroom, got home and noticed it was the Asian version, and they only recognized the mistake after the negative reviews on google and facebook. They told me to come up with the phone to exchange or give me the money back. I went to them and I was asked to pay 10% of the value of the phone because it was bought out of the showroom and unpacked. I do not recommend.
