Edgar's:Samsung A30s

I bought a Samsung A30s on the 02nd of May 2020 it amounted to R5000. I used it from that 2nd of May until 13th July 2020 but on the evening of 13th the screen went blank then on the 14th i took it to the store because i didnt know what was happening. It has now gone for repairs and im told to wait for 21days. Imagine the inconvenience of not having a phone more especially after i had bought a very expensive one. I don't undertand how a new phone/new model can give me problems within a space of 2 months. I just hope my quiry will be resolved and when it comes back it will be fixed or i will be given a new phone infact i dont even want that A30s anymore because its quite evident that it has factory faults. I would like to actually exhange the phone for another model. Please do a follow up because I'm not happy with the experience.
