A53 frustration- round 2 without a phone

I currently have a 24 month contract with Telkom for the Samsung A53 which I got on the 20th of May 2022 which means my phone will be a year old next week and the warranty will expire.

January 2023 I returned it to Telkom @ Festival Mall which sent it to Bradian Logistics for repairs. It turns out the motherboard had issues, they had to wait for spares and I sat without a phone for an entire month. To top it off I had lost a lot of my photos and documents. My phone is currently in for repairs for the second time this year as of the 1st of May 2023, I handed my phone in at a Samsung branch and it is the LCD now as my screen just went blank/black. I was once again unable to retrieve anything from my phone as it would not read my files the same as the first time. The branch advised it would cost R450 to backup, how is that a cost to me when Samsung device is the problem????

I would like to know now if anything happens to this phone again after the warranty expires who is liable to fix this faulty device that has given me issues twice in this year and in a span of less than a year? How do I sit without a phone for the second time for nearly a month again because the branch advised I should follow up the end of next week which will be 3 weeks without a phone???

I am highly frustrated at this point as Samsung is supposed to be one of the top brands but I have only lost since having this phone and I feel like if this device has given issues twice so far, who can assure it will not again in 3 months when the warranty is no more.
