Worst car

Am not happy with Toyota I bought Toyota agya less than 5months ago now I have logged a complaint about the starting of the car now it's having this annoying sound that I don't even know where is coming from bought the car when it was on 24000km now it's on 29000 it means when I get to 50000km I will have worse problem this is my 3rd car but I think buying Toyota for my business was the worst decision I have ever made because I can't be having problems with a car that I drove less than 2months💔💔
