Extremely poor customer handling skills by a "manager"

I went to Huawei Sandton store to buy a phone on Thursday(06/06/2024). I was told certain apps from google work(which was a lie) and because of that I decided to buy the phone and went home. As soon as I arrived at home I started to set up the phone and realized that those Apps to do not work so I decided to take back the phone 2 hours later after I bought it. I was shocked when the manager refused to take the phone with nothing wrong on the phone, we had a very long argument in front of other customers(I would be surprised if those customers proceeded to buy the products after what they saw) and she could not give me a straight answer why she was not taking the phone and give me my money, it felt like my rights as a customer where being violated. A junior employee had to intervene as what the "manager" was saying did not make sense. I understand it could be difficult to sell some of your products because of the issues with USA/Google, but the cherry on top is when your "manager" with extremely poor customer handling skills has to face the customers and say things that don't make sense.
