No exchange of batch default within 7 days

I brought my Samsung A71 at Cell C and when it was over heating was advised to take it to Samsung which I did. I was told it was a box default and needed to take the phone in. So I sent my phone my phone was later sent to We Fix. I then saw that my phone was being repaired as a single sim phone yet I have a dual sim phone and went to the store and asked them to make the change. And when I got a message 2 weeks later to fetch my phone my phone wasn't sealed right and the seal was sticking out. I then was advised to book the phone in again. So I did so. I then emailed samsung to notify them about the service I got and I then got a call from We Fix manager he then told me it was just dirt and its sorted. When I went in to collect my phone there was a huge gap on the side of my phone and the manager then told me its nothing major and it doesn't effect the quality of the phone. I refused to take the phone in that condition. The next morning I got an sms stating that its my second reminder to collect my phone. So I went in and what they did was take my back protector and cover the gap. I then ********** my cover and told them it needed to be fixed. The manager told me it will only take one day and needed to come back the next in to what I did. To then find out my phone has multiple chips on the side of my phone. And then got my dad to come in coz it was clear I was not getting the right service based on my age. Only when my dad came in did a manager from Samsung come to We Fix to see the phone. And even then the manager told me its just a minor chip and not a major chip and I'm just being fussy. The manager at Samsung just said they going to take it up and still never did up till today. We Fix higher management was only notified about this after my dad came into the store. Higher management at We Fix got my phone delivered to me to use until the new back cover arrives. I then decided to download my apps and put my sim cards in to then find out my phone does not read 2 sim cards and when I'm on an app it goes off after a while. I must say I'm still without a phone that works and its 4 weeks already and all I get told is that they understand and will take it up and never does.

Samsung then issues a broken device again within 7 days I logged in a complaint and then in January 6th I get a call that I must collect my device. I could not go in due to having covid once I recovered I went in and then they tell me there's no such thing on their system. Now when I call them each day I get a different story with no mangers and no supervisors in duty and their floor people cannot do anything. Now they refuse to give me the recording of all the calls coz they don't want to replace the device and making me look like I'm a ****. I'm really tired of calling them. They also are declining after I requested all the calls coz they know they wrong.
