Bad customer service

I bought a Samsung galaxy A04e on Friday 05 May 2023 at Edgars cradlestone. The phone is taking too long to charge. I charged it from 06:30 and the battery capacity was 15% and at 10:00 the battery capacity was 90% full. I observed the charging behaviour of the phone from Saturday and no improvement. I took the phone back to the store and the lady storemanager who refused to give her name made unpleasant allegations. Firstly she responded with an attitude when I was explaining the problem. We then agreed that I leave the phone at the store for them to charge and observe how long it takes to be full. The battrey capacity was at 60% and they plugged it on the charger at 14:40. They called me at 16:11 to tell me that the battery capacity capacity reached 100% and we confirmed the times. I then asked them does it look normal to them for a phone to charge that long (1 hour 30 minutes) to charge from 60% to 100% and again the response came with arrogance that it is normal and they don't see anything wrong. I wonder how stupit can one be to think that way. I came back with the phone and tomorrow I will be going back there hoping that my daughter will use the phone until there is no power left and request them to charge it from 0% to 100% and record the time it took. What a waste of time and petrol.
