Poor poor service with faulty item

Bought a Garmin 245 watch. Received it on 2021-02-24. Returned it on 2021-02-25 due to faulty unresponsive buttons. Received email from takealot saying they are out of stock and i can choose to either have the watch fixed or have my account credited. I then sent them a screenshot of their website showing that they do have stock. I received another email from them wherein they admit to having stock, but it is now suddenly sourced from a different, more expensive third party. My account was credited. It’s not my business where the watch it sourced from. I made a purchase from Takealot and Takealot must sort this out and deliver the watch to me for the price i paid
