Invens smartphone Max8,2+16GB

Good day Last year 2020/September I bought an Invens smartphone MAX 8,2+16 GB via takealot and I truly regret it. Reason being, the phone constantly wants to me to be reset or otherwise it will freeze before it even gets to 13 GB. I even bought a 64GB memory card privately hoping things will get better butt no luck. The Invens smartphone does not except any of the memory cards which I constantly have to format and still not wok. This is the worst ever product!!!
