Worst service ever - if I could rate you 0, I would

I have been struggling with Takealot since Aug 2022. I had purchased a Bennet vacuum cleaner in November 2021. I had issues with the vacuum cleaner so I sent it back and it was replaced with a brand new one. Not even 6 months later I experienced the exact problem with the vacuum cleaner. This time when I returned it, I requested my money back as I did not want to experience the same problem every 6 months. They refused to give me my money back and insisted on fixing the item. The item kept been delivered to my place and I kept returning it . Please bear in mind that the last time I sent the item back it was never returned to me in Aug 2022. On 26 July 2023, I called the returns/delivery dept to ask them where it is and they said that they're investigating with the courier company. I didn't hear back from them. I called back on 21 Aug 2023 and I got put through to someone by the name of Rhoda, she promised to assist me and get an answer that day. What a lie because I never heard back from her. I was sending emails from 21 Aug 2023 and no response. I called back on 23 Aug 2023 and I spoke to someone by the name of Aqeeb. He also promised to help me. He eventually came back to me saying that the item was indeed delivered to me sometime during the course of last year, so I asked for the proof of delivery. He advised that it was now out of his hands and that the Returns dept will be in touch with me, this was on 24 Aug 2023. Again radio silence from Takealot. I called back yesterday 28 Aug 2022 and spoke to Sizwe who advised me that the item was delivered to me on 21 November 2021. That is when I lost it! It's been more than a year!!!!!

Does no one in Takealot know what they're doing?

I have now come to my limit with them and I want my back immediately!
