Poor Client Service by McCarthy Ford The Glen

I went to McCarthy Ford The Glen to fix my car with overheating issues, the parts department advised me to buy parts before I took the car for a diagnosis which I did, then the technicians finally did the diagnosis which reported that my car needs an engine replacement. After the diagnosis was complete I got called and I instructed them to not proceed with fixing the car as it needed an engine replacement. When I went to fetch my car, the parts department forced me to take the parts even though the parts were not needed by the technicians. I asked them to take the parts back and give me my refund, they refused to do this (this is against the CPA). The car was also handed back to me with parts under the hood disassembled. They didn’t have the decency to put things back to how they were. This is poor customer service. Now I have car parts I don’t even need. I am not a mechanic
