No stock, so go away

When I bought my Samsung Galaxy A20 cellphone in 2020 I used takealot to buy a protective armour case for it which is excellent as it protects the phone very well. My brother gave me his Samsung S10 cellphone and I wanted to buy the same case, but it is not available for the phone, but available for the S10 lite and S10 plus. This is ridiculous as S10 was the first to be sold followed by the other versions. Useless site, also unable to order it for me.
