Call the clown that did the job and have them look at what they did.
You not very help full the clown as you replied replaced only the parts that needed to be changed we had a technician from BMW as well that are also confused to why this is happening
Let's review the problem. You had the BMW serviced Now you're car won't start. It was running before you had it serviced. Maybe it's the flux capacitor. Technicians are famous for not cleaning up the carbon that builds up on them.
If it turns over and does not start it could be your crank angle sensor. If this is not working you will not get spark at the plugs and engine will not start.
