Volvo has poor customer service and inability to fix the car

I bought a Volvo XC60 demo for my wife in 2019 from Volvo on Main road in Bryanston with very low mileage of just under 10,000. From that time this car has had endless problems and wondering whether Volvo has got the expertise to fix this car. Last year in 2021 the car was at the dealership (Bryanston) for 7 months and in that 7 months were promises after promises that it will be ready next and then its next month and so on till finally we were told they had ordered a new engine which also took a month to fit from the time when we were told the engine had arrived. In April 2022 took it for a service again in Bryanston and the following day the car failed to move and just a lot of smoke coming out, the tow truck picked up the car on the road side as i had tried to take it to the dealership. Its now 7 weeks already without a courtesy car for a car that am paying for every month and incurring extra expenditure on uber and sometimes hiring a car. What are my options? Does Volvo know what they are doing? or are we being taken advantage of? One thing i know Volvo doesn't care about the customers, we don't get any feedback or updates unless you call and even then there's nothing new
