It's the horrible experience today beyond what you can imagine. I booked an appointment today at 11am for oil change only. Was told to pick up the car at 1pm, so far it is OK, we waited for two hours, was hoping to pick up the car at 1pm, was told again to come back to pick up at 5pm, so far emmm, if you would like to hold the car for 6 hours, you should have let me know it when I called in for appointment, so we can make it in plan. OK, when we came back at 5pm, they kept us for another half an hour, because they even didn't start it yet, we wanted to decline the service, but they said they just started it and take just half an hour. Well, if you are too busy to fit me in, that's totally fine, but do not act this way, you'd better respect your customer, you have hundreds of ways to make this better, at least you can tell us the right time so we can pick up the car, instead of wasting almost the whole day to deal with this. You won't lose customer so you say yes whatever customer want, well, you will lose this customer forever in the future.
