Takealot terrible service

I purchased a Samsung note 20 from takealot in Decemeber 2023. Takealot confirmed that the phone is under warranty for 36 months, meaning until December 2026. However in July 2024 the battery of the phone had completely swollen up and would switch off and on by itself. The device became useless. I reported this to takealot who in turn referred me to samsung. I drove to 3 different locations trying to find a samsung store to assist me. Finally I was told that samsung could not assist me as my device was an "overseas model". This was never communicated to me when I purchased the device. I then informed takealot and I was requested to return the device. That is what I did. I was later informed that I need to return the charger of the device aswell. That was around 17 July. Since then I've had to reschedule four times for the collection of the charger because they simply do not show up to collect the charger. I informed them that I am sitting without a device which is becoming increasingly difficult to deal with. Not only am I a full time student, I am also a mother who cannot get in touch with her children during emergencies. They keep on apologizing for the inconvenience but nothing has changed. I am starting to wonder if this a tactic for them not to repair/ replace or refund me. I paid R15 000 for the device and it is not something that I can just let go.
