Terrible experience from Management for a Warranty

Good afternoon I have purchased a Connex Swiftbook on 27 March 2021. I experienced issues with Laptop not connecting to the internet and took the Laptop back to Hifi Corp Cornubia on 13 November 2021 which was booked in for repairs. I went to the store on 8 December 2021 to enquire with the store on the progress on the laptop and was told it is still with the supplier. I received a call yesterday 13 December 2021 to inform me that my laptop was repaired and I can collect it from the store. I went to the store today 14 December 2021 only to test the laptop and the laptop was still not connecting to the internet. I spend over 45 mins in the store. The store staff Thembi tried her best to assist me, making phone calls upon phone calls. Only for her to contact Fabian from SMD (I think that’s your supplier) to be told that the software was updated on the Laptop and when she asked about the fault the Laptop was booked in for he did not know what she was talking about, she told him the fault was recorded on the repair document. He told her to book the laptop in again which I refused as this laptop was already booked in for over a month and to be without a laptop for another month is just not fair upon me. He then said he is sending through a replacement unit. Now this is where I have a problem, I have been to the store on 3 occasions for a fault which is not mine, now you want me to come in back to the to pick a new Laptop on a separate occasions, who is bearing the cost of me coming in on multiple occasions for this (the price of fuel is ridiculously high and also my time involved). I requested for the Store Manager (which I requested 3 time before and she never came to assist me, as she was busy in the stockroom), I told her I did not buy the laptop from the supplier, I purchased this laptop from Hifi Corp and you guys need to assist me and offer me the after service I deserve as a customer of you, if this is the case we all can go directly to the supplier to purchase a laptop and there won’t be a need to purchase an item from you as Hifi Corp do not value their customers and offer them the best possible service. She then quotes the CPA and tells me that is according to the CPA. So I asked her where is the CPA when my Laptop was booked in for over a month and it is still not repaired and Hifi Corp is not assisting me as their customer and keeps on referring me to your supplier, so I need to ask the question, where I did purchase this laptop from, I do understand that suppliers bear the warranty for an item but this laptop was purchased from Hifi Corp and I am a customer of Hifi Corp and not the supplier. She was adamant in saying there’s is nothing she can do and she walked away, (please check your cctv camera for reference here). Honestly speaking she does not know the correct and proper way of speaking and treating a customer as she walked away from our conversation. She could have offered me a new laptop and when the supplier sends the replacement laptop she can replace the stock, simple I would have been satisfied, but she offered no assistance other than quote the CPA. I referred this matter to Hifi Corp customer service ref no. *** still awaiting feedback.
