Poor service

Vehicle went in for 60000km service. Car feels like no service was done. Changed battery on remote which was not faulty. Reported feedback no response. Took my car back today for them to sort out faults but car was driven for 21kms. Seats were back like someone had being sleeping in the car. Report that my aerial needs to be changed which they could have told me when the car went in for service. I think they just want to make money of the people. Very bad service. Now i feel like doing private service rather than a dealership. ***
