TFG - Selling faulty products + Poor service

My mom purchased a brand new Huawei Y6P from Foschini at the Pavilion mall in Durban on 30 July 2020

1. Multiple apps not available on the phone - eg. navigation and search engines (understood that Google services are not available, however the advertised substitutes are also not available) - reported on 1 Aug 2020 - 3 Aug 2020 at Foschini. She even visited the Hauwei shop at Cornubia when the workers at the store could not help 2. Downloaded multiple apps and within a week all apps went blank 3. All apps stopped functioning. 128GB were full in less than two weeks. She hasn’t uploaded any of her data as this phone has been problematic 4. The decision of the store has been to take the phone in for repairs. How are you selling a faulty product and treating it as a client fault. This phone is not broken, it has been faulty from the onset 5. No offer for a new phone has been made. TFG is selling these products, this treatment of clients is unacceptable.
