Land Rover West Houston

I own 2020 bmw x7 m50i. I bought my car from auto nation ford dealer and i purchase 5 oil change with some discount at that time. They told me i need to go to auto nation landrover dealer for an oil change because my car needs a special tool. I went to autonation landrover dealer for an oil change. After that my car started leaking oil. I taught its an engine problem and my car has warranty so I took the car to the bmw dealer and they told me who ever did the oil change they have spilled oil during oil change and made a huge mess under the car. They’ve cleaned it up and i came back home. After that car was still leaking oil so I took it back to bmw dealer. This time around lifted the car and find out they installed wrong oil filter and a wrong o ring. I discuss with the general manager and he agree they never use oem parts ANY CARS even with 200 k cars. Bmw dealer quoted me to fix the issue and they had to completely clean under the car due to lots of oil spill/leak. It cost me $500 and so I took this bill to the landrover dealership. They refuse to reimburse me this cost because I did not take the car back to them to service it. I just couldn’t trust them to do anymore work on my vehicle so i decided not to take my car back to them. I have also spend so much money to get my drive way clean up/ degreased and not to even mention time I had to take off from work to take care of this issues!! I have only asked them to be responsible for the charges to fix their mess up!! Which they refuse to pay!!!
