New fone problem and the telkom shop cnt resolve the issue to my satisfaction

I bought a fone on contract Oppo A78 at telkom Klerksdorp shop on the 21 march 2023 .4 days later i experience problems. When the fone rings it doesn't show the answering button meaning i cnt answer the fone. I took back to the store on day 6 and they tried to check what was the problem and so forth, suddenly it work and the lady didn't do anything to fix it, 9 days later it started again with the same problem which was the weekend, on day 13 i when back to the store they tried again to see what was yhe problem and told me that if it was within 7day they were going to apply for whatever so that i get a new fone,forgetting that i was there within that 7days that their talking about.

On that day 13 which was yesterday they told me that the only solution was for the fone to be taken for repair that will take 7 to 21 working days, i tried to explain to them that my job is online and i work asbi earn meaning no fone no work and they told me that there is nothing they can do except that the fone must be in for repairs and i cnt live for 7 to 21 days without a fone.

Am very disappointed and frustrated at the moment because i took my fone back to the store within 7days and no one is considering or taking the responsibility to say the client brought back the fone the consultant didn't do her job to solve the problem. Hello Peter i really need help on this matter. My fone brings food on the table for my family i cnt be without a for for 7 to 21 days. Am stucked with a 13 days new fone.
