Parts available for GWM H6

On 16 March 2022 i took my GWM 2015 model 1.5T to Motorama as the vehicle was serviced with them in January 2022.My insurance assisted me to transport the vehicle to them. I have been waiting since then for my vehicle as every time the part that they get is wrong. When i call i speak to Sydney at parts and every time he says that he will update me in what is happening. The part that is damaged on my H6 is the oil cooler. Can it be possible that there is no part available for my vehicle in South Africa. I thought all Gwm is easily available.
