Buy an Item with a 12 months warranty - Takealot refuse to refund/replace or provide feedback of why?

I have bought a Replacement Backlit Keyboard for HP EliteBook 840 G5 G6 745 G5 G6 That cost R 899. I have worked with this keyboard for 9 months and then some of the keys stop working. I have requested Takealot to fetch this keyboard from me on the 6 of march 2025. On the 18th of March the Merchant received the keyboard took for every to reply. They rep**** that they have tested the keyboard and they agree it is faulty and they will get back to me with a decision. This was done 2 April. The next minute the keyboard is delivered back to me. I phoned Takealot just to find out the request was cancelled. No Explanation no refund no nothing. I am retrenched and I use the laptop to do odd jobs here and there. I ask to speak to someone that can explain to me what is going on. The operator advise me that they are not allowed to give me the Merchants no. Nor is she allowed to put me through to a manager to advise me what is going on. Honestly what is going on. What happened to service. On this keyboard on the takealot website there is a 12 months Warranty. 12 months is not yet over?????????????????????????????????????????????????????????????????????? Aleast provide feedback on way you refuse to replace or refund the keyboard. That is customer service. Now I pay R900 - they item last 9 months and I get a broken keyboard back wiht no explanation. Take a lot will you except this kind of service ???????????
