I needed a valve body done and a B service as well...

I needed a valve body done and a B service as well, I had that work done here a few weeks ago. First of all I brought it in on a Monday they guaranteed me that it will be done the next day because I was planning on driving my car out of town, well they didn t finish it when they promised me they would. So I finally pick my car up pay Over 2300 to have it fixed, not to mention I was going to leave town once I picked my car up, but couldn t because when I got home something told me to look under my car engine, and when I look it s pouring out tranny fluid excessively, so guess what? Had to postpone my trip again because the work was not done correctly. So with that said I had to wait until the next morning to take it back to the service department, they said that they forgot a screw or they torqued the screw or something, they apologized which didn t seem sincere, and offered me a detail. My real concern is what if I would ve just jumped on the highway for my out of state trip and never noticed that leaking?? I m sure I would have been on the side of the road in a bad position. And it makes me upset because I took my 2012 c250 to Mercedes Benz of Denver to avoid taking it to a independent Mercedes dealer so they wouldn t mess it up, but they same thing ended up happening to me at the dealership only thing is it cost me 1500 more to take it to Mercedes-Benz of Denver, but they still messed up and didn t seem to care.... uncertain if I ll ever go back.
