Absolutely pathetic !!!

Pathetic service !!! Please don't trust your car with this service department!!!! My car has been ther for 4 weeks.after calling desperately for my car ,they sorted authorization within a few hours! My car is still there waiting for parts this is now week 5.needless to say my last service took 4 weeks and came back with half a tank empty then it was sent in with.i have delt with two different people within 2 years and its safe to say that this service department has no 'service ' delivery or professionals ...
