Bad experience

I have had a very bad experience , I took my car in for service and they reported a possible oil leak, they advised I should drive for about 500km and bring it back in, when I did that, they confirmed there is most definitely an oil leak I must book it in , 12 of march 2025 I took the car in , there is no curtesy car , no car I could hire as my car would be in for two weeks, such a huge inconvenience!!! 26 march got a call to say the car was ready, picked it up and next day when I drove it, it made such a terrible sound as if there was a zinc I was dragging under the car!!
