TEMU -Poor quality and no customer support

I recently pruchased an Android tablet for Temu, when I received it the screen was unresponsive , I reached out to Temu and they opened a ticket and closed it 3times. They said return the item to get a refund whic is all well and good however in order for me to have recieved theur defective producst I paid an additonal R300 for customs which is non refundable and TEMU just says its not their problem arrogantly and wont address the main issue that I will loose money to return their defecitve item
