Extremely aweful service

Took my car for a service, major service would cost alot. Get there early firat car in line. Get signed in. Everything is fine. Get a call at 2pm they are going to be late with my car, bare in mond i was 1st in line. Then at 3pm another call oh we lost your car keys. Disgusting all around, chatted to a Frank when i got there, he said we will chanhe out locking do a discount no labour charge, and we will come get it from ur work place. Lucky they found the key, The day comes when they need to fetch it fir the service, they only arrive to collect at 10:30. I said i needed it back by 4, I'm worries it wont be done in time. 16:50 car still isnt with me, i call and get told oh they finishing now. When i ask about the price, the discount he knows nothing. Why its late? He replies what do u want me to do? I got really frustrated at thay attitude. Its been disgraceful service from a huge company. I will never return there. They have no clue how to treat a customer at all. Let alone one where they lost my keys. Disapppinted and irriated, wasted my time.
