faulty products

I'm writing this with a heavy heart and so much disappointment. I was really hoping and praying that takealot will be able to assist me. I returned a laptop/tablet last week without the passive stylus because we lost it. The reason for the return is because the tablet didn't switch on, stopped working and charging. My daughter uses it for school as they don’t use textbooks. On Thursday I received an email from them (takealot) about the said missing item, I responded that it was lost and then today sent them a DM on Twitter asking for feedback. I pleaded and begged them to please either fix it or replace it without the said missing item. My daughter is really missing out a lot on school work cause we’re still waiting. And then to my shock I was told that they 'regrettably can not assist as there is an item missing. I understand that maybe they can't replace it but I bought this tablet/lapton in December 2021, so a warranty is still valid. I even asked that they please at least fix it instead of replacing it or if they can't do that then replace it without the passive stylus. This laptop is not even a year old and now we will be stuck with something that's still under warranty and yet they wont even try to assist or meet me halfway. I was not even looking for a new one just that they check the problem with the one we sent and they fix/repair it. the amount of disappointment and sadness I have can not even be put in writing. I am so emotionally exhausted and drained. My daughter is behind with her school work, I don't even have the funds to either fix or replace this one. I so wish they could just fix it, now what must I do with something that's not working? how is my daughter going to do her school work, she's already so far behind.
