Bad service, factory fault (Sensor)

I bought an Omoda C5 in May of 2025 from Group 1 Kuilsriver in Cape Town. I took it for long distance drive to the Eastern Cape on the 21st of June. It was fine up until Beaufort West. Started giving me problems from Beaufort West to Queenstown. I took it to the nearest dealership and was told about Crank Shaft Sensor that is damaged. I have been waiting since for repairs, and no one wants to take the responsibility for the car that is still under warranty and definitely not my fault but a factory fault. I ended up leaving the car in East London, back to Cape Town with the bus. They are refusing to give me a curtesy car or pay for any expense that I've incurred. I am even told to pay R700 by the dealership in East London for test driving after fitting the new sensor. I am even thinking of returning the car to the dealer so that they can deal with their problem. Can someone from Omoda give me a call so that they can understand my frustration.
