A/C stops working?

Hi, I own the vehicle listed above. Three months into owning the car the A/C stopped working took the car to Hyundai dealer and they said it seemed the blower unit failed and ordered a new one. A week later they replaced it and gave me back the car that same day on my way back to work it was working intermittently so I turned around and went back. They then said the cable was fixed hard enough. I then left skeptical about a month a half later the A/C stopped working again for about 3-5 days now it’s back working but it’s a game of roulette if I turn on my car and the A/C works or not and it’s been less than 6 months of owning this car.
