I phoned upgrades to upgrade so i could find black Friday specials even that was difficult to get good deals

I phoned upgrades to upgrade so i could find black Friday specials even that was difficult to get good deals. I also complained to Vodacom regarding rewards/loyalty packages for loyal customers. Vodacom responded by referring me to their app. I'm on the app but it is not user friendly for those with visual impairment. I'm visually impaired and the app you refereed me to does not accomodate me at all💔
