The worst service

I purchased a car with primo cars on the 06/04/2023 and two days later I had an issue with the coolant to which I reported and 4 months later I still have the same issue. The car has been to their workshop more than 4 times and they tell me a different diagnosis every time but the issue is never resolved. I was referred the sales manager who is absolutely not helpful, does not respond to email and I always have to follow up. Every time they take the car to check it. they leave me without a car and telling me they don't have car hire services. The sales process was very smooth and effortless like any other sales transaction, but the service afterwards has been pathetic. Thier secondhand cars are so pricey but not in good condition. I regret the purchase and would not recommend primo cars to anyone
