BRAKE PADS A BIG PROBLEM

Took my car in for service at 12000kms , brakes were grinding and supposedly had to be replaced. I was told by the service manager that GWM are fitted with cheap chines brakes and that's why it needed to be replaced so soon . After they change it it made terrible squeling noises took it back 3 times and they did not recitify the problem. Car went in at 24000kms all fine except that the tyre pressure sensor keeps breaking so whats the point of this device!Had to have this replaced at the 12000kms service. They forgot to change the spotlight bulbs at 24000kms. Already had all the light bulbs not working at the 12000km service. Brakes failed on Friday and we were nearly in an accident . This was at 34000kms. Car back in with discs cracked and worn brake pads again. Its not possible to have gone through 2 sets of brakes pads in 34000kms. GWM not interested and state that I have to pay. Crazy as I bough this car brand new and as a women feel very vulnerable driving this vehicle if there are fault brakes. Believe GWM should resolve and pay the R7000 that I have had to fork out. I cannot afford this especially on a new vehicle.!!!
