Don't buy a Huawei phone

Telkom sold me a huawei phone as best on the market, told me I can install any app on it. Even showed me a demo device that it has all the apps already downloaded. Bought the phone, have experienced major issues since then. Tried to return it, they refused and said they will send it in for repairs (brand new phone). Not compatible with needed apps. Paid a fortune for a phone that doesn't work. Just recently got kicked out of whatsapp for not using official app. Lost all my important conversations.
