Land rover is the head master of bad service

Land Rover Bryanston gives the worse service ever. I took my vehicle for minor problem and they told you it will cost 30k. the car spent a week at the dealership and it was ready according to them on the 20/12/2022. Upon collecting the vehicle i noticed oil leak on my garage and the vehicle could not reverse ( calibrating warning ) because of the Christmas holiday i could not return the vehicle and now they cant fix my car or give me a loan vehicle sorely because my car is out of motorplan.
