unfair treatment

Good day On the 02nd of October 2019 I purchased a J4 Samsung Phone for the value of R1999. Then on 6th of August 2020 I brought the phone in at the same store I purchased it because the phone had gotten very hot at the back the previous night and would not switch on,it was only displaying the samsung logo circling for hours but it would not turn on. I left it as such and the next day I noticed it was no longer on so I attempted to charge it and on the screen it showed the charging thunder like sign but it was not counting to show that the phone is charging as it normally does when I charge it .So I removed the charger and inserted it again to see if it will do something and it was not showing any sign of charging,it was basically dead. That is when I decided to take it back to the store ,when I got to the store I went to the lady who sold the phone to me and she went with me to customer service to have them book the phone in .she explained the problem to the customer care lady and she took my ID and receipt made a copy and took the phone along with the box,However she told me that she cannot book it in as she either doesn't know how to or she is not responsible for that.so the person who books phones in is on lunch so she will give her the phone when she comes back from lunch. Now ,i had just come out an minor operation I was not prepared to wait for someone to comeback from lunch even if i wanted to ,so the lady advised me to leave the phone with her although she could not give any form a receipt that she took my phone she indicated that i will receive a sms of the booking and i can come in at a later stage to get a receipt .I don't work for Game and i do not know the procedures so I handed her my phone without any inspection at my presence or me getting a slip. So a week ago or so Game contacted me to tell me that the repair will cost me R2400/R2700 not sure of that figure to fix the screen.I was puzzled and could not understand why they called me about the screen because i took my phone in as it was hot and not charging not for the screen So yesterday i took a drive all the way from Pampierstad to GAME to try and understand what was happening. Anyway the lady at the customer care called the repair people and she told me that because my phone has a scratch on the screen I need to first pay for the damage that will occur when the technician open my phone to troubleshoot it so they will break the LED when they open the phone ,but my phone was taken in without any inspection of any sort while i was at the store. So the R2400 or so that I have to pay is not even for the problem that the phone had ,it is for a damage that will happen when they open the phone, Iam not at all happy with the service and treatmentI am getting from GAME ,i was told about the about 12 months warranty now they say my phone has a crack basically GAME cannot fix the charging problem becauseI I cannot afford paying the R2400 first .Today is the 2nd of september 2020 the phone has only 1 month remaining for the warranty to expire and the lady on the phone told me that if I want them to return my phone from the repairers it can take long they can't even tell me how long it will take. So basically it will come back unfixed and after the warranty expires it will no longer be GAME s concern. I need my phone to charge .If GAME cannot assist me in that regard please I would like to return the device for my full refund. I'm not even going to try and ask for the rationale behind a phone costing R1999 and the repair of its component major or not costing more than the phone . I am very disappointed and hurt by the service I received.
