Refusal to comply with the consumer act

I bought a Huawei Y7 2019 cash at Cell C Malelane 2days ago. I requested to swap the phone for another brand due to the fact that all Google services will not be provided after the loose restrictions from the USA lapses in 4 months. The big showdown between America and Huawei. No updates will be available meaning the platform for receiving gmail, WhatsApp and google Docs will not be functional. This was the sole purpose of buying the phone. I live in an area where there are no landlines and I solely depend on my cellphone for income. Does Cell C negate the consumer act? If you buy a product for an intended use and it will not be working that you cannot exchange it still with in the 7 day period. Staff at the branch has no intention of assisting, the manager is is leave till end May! Customer service says you can return and swap but the branch refuses. On another subject, the LTE services in the whole of the Underberg area is NOT working for 2 months now. They deduct from your account, with NO service and NO answer when they will fix. Come on Cell C, you are seriously losing loyal customers!
