Return Policy: Lie

I bought Samsung a3 core on 21/12/20 and was told I have 7 days to return it if not happy with it by sales man. I downloaded Screenshot Easy from google play and some features were not able to turn on as it says "enabling that will slow down the phone". When you charge the phone you must be having more than 2 hours for it to be full as it takes a lot of time when charging, the manager by the name Jarques told me that's my problem and not the phones problem and said I was supposed to read the phone's specification before buying as if I didn't.

I read about "Client's happiness" about devices bought from makro and it is said that if you are not happy about that you can return the device. At this point I have 2 issues: Apps limited functionality and battery/charging time. I wasn't assisted at all except being shown the door indirectly by the sales team and I am not happy at all.
