PlayStation complaint: my system being a lemon and not working

so i bought my ps5 digital in late april. i only had it two weeks before it started crashing and couldnt play any games so i opened a repair ticket and then it came 5 days later and so i sent it in to the service ctr in laredo to have it repaired and it took them several days so after receiving it back from the repair place and turning it on and downloading a game again to see if it works and to my astonishment it wasnt fixed and actually it was even worse then before. previously i could atleast play the game 50% of the time. now i cant even play any games. like wtf. so i reached out to playstation direct to get a refund because its obvsly a lemon and they pretty much said go screw myself. and said no even tho its being in repair the whole time since having it. so i will be suing you and filing a compliant against PlayStationsony for selling me a lemon for 600 dollars and not fixing it or replacing it. i will be filing a complaint with FTC, BBB, and reaching out to a lawyer. how they treated me. A lifelong member of playstation for 10 years is unacceptable
