Dissatisfied customer

Bad service received from agents to the manager. Cellphone after 2 months just died. Requested assistance as this is a brand new phone. After struggling to get assistance and being promised that someone will get in touch finally spoke to someone today. Keep in mind the issue was raised on 3 Jan 2023. Got hold of shamiela jafta today who was not very helpful and wanted to bring her point across more than me making me feel like I'm at fault. Stated I need to pay a courier to deliver the phone to them if not need to drop it but can only do so the day after and before 12. If she can't fix it will send it away for up to 21 days. If it's within warranty they will pay for it if not I will pay and if I don't want pay need to pay a cancelation fee. When I asked for a supervisor or manager she informed me she was the manager as well. She is the IT support and manager at the same time. I was appalled at her service, the way she spoke her and her sarcasm
