Leaving it to the last minute!

I dropped my vehicle for its service at 6h45, asking to pick up at 3 and requesting quotes on two biggish items, brakes and battery. At 2, am hour before I am expecting to pick up the vehicle I phone to find out what is going on. Empty apologies and excuses later, they don't have a battery in stock... so I will have to come back, also for the brakes! This is not Ok! You don't provide transport to my work so I have I uber which is an additional R400 ... all because the ball was dropped, even though I had a dedicated service consultant. This is not customer service!
