By far the worst customer support and after sales service I have ever received. Absolutely shocking. I pre-owned ordered a mate 20 pro which had the green screen issue, I have called in several times to have it fixed. It is a known issue, I have spent close to a grand for this phone and they have no offer of direct replacement or courier collection and delivery on the same day or any option what so ever. So I don't have a phone and they say it will take a week or two at worst. I send the phone in and have to buy an interim phone for my self as I'm phone less now. Nearly a month goes by, still nothing. Have requested call backs from seniors several times, no contact. Have requested a reasonable time frame or resolution, they have nothing to offer, can't even tell me when they will call or when they will send my phone back. Won't even provide refund. Should be shut down. THE WORST COMPANY I HAVE EVER DEALT WITH. 100% AWFUL.
