PATHETIC AND USELESS SAMSUNG SA

I bought a samsung phone A01 in October 2020 after a year, the battery takes long to charge. I took the phone to samsung on 22 January 2022 and explained the situation, they advised me it will be sent for battery replacement, after 21 days they sent me invoice that i must pay for drop damage????? I was shocked, where is this now comming from. customer service tested the phone and there was no damage beside the battery is slow. he confirmed and gave me a copy of my receipt with confirmation then again they called me that they will not fix the phone if i do not pay the amount of R1190. Pathethic!!!!!!!!
