The best service or not?

<p>I took my Mercedes E280 to Gariep Motors in Kimberley for a service on the 30 June 2016. Upon receiving my vehicle at about 17:00, I drove off home,luckily just 5km away from the dealership. When arrving home I noticed smoke coming from my bonnet and immediately parked the car and investigate. The whole engine was full of oil, the oil was still splashing out at the bottom. I though it was at the oil sump. The road that I came with had a long oil streak that followed me. The engine had no oil? I immediately called the service agent and he sent out the 24hrs service vehicle to my house.They filled the engine with oil and noticd that the oil filter was not properly fastened,seal popped out. I asked them to take the vehicle back and verify that everything is still fine with the car.Since my car came back after the thorough check-up my engine temperature is jumping up and down.I called the service manager to inform him about it and he said that the temperature is fine.My car never did that before,what if my engine heats up and gets damaged?Who will be responsible?Apart from that my wife is fuming because the paving in my yard and at the entrance has a huge oil spill/mark that Gariep Motors tried cleaning but it is still there.I need my car to be fixed and come fix my paving please.Mercedes is suppose to be a top brand, but with this treatment I received I doubt that 200%.</p>
