Land rover doesn't care about their customers!!!!!

Thursday last week I was told to stop the car because I called them the engine warning light is on again for the second time!! The 1st time I took the car in and they told me they will change the filter which they told me they did, two weeks after the light came back which makes it obvious that they didn't change the filter, and now I'm sitting in my house from Thursday waiting for land rover assist to come and take my car, the lady that I spoke to now just told me that I need to phone my dealership to confirm that I have taken an extended warranty, I'm thinking if my car broke in the bushes they will be still waiting for the confirmation and not doing anything is that how they treat their customers!!!!
