Poor car service

I took my car for service yesterday. I would have expected the service agent to call me and update me on the progress or even call me to inform me that my car is ready for collection. At 16:00 I called to find out how far they are with my car. Only to find out my car is ready for collect. Upon my collection I was then informed then that my brake pads need to be changed, my service agent did not even bother to inform me, I would have told them to fix them and I’ll pay on collect. What makes it worse is that they didn’t even wash my car. I collected my car in the same state I brought it in. I’m beyond disappointed with the service I received.
