Client Expectations

Took my car in for a service and to fix an oil leak on the Monday, was told it’s a 2 day booking. On Tuesday they tell me they need to remove the gearbox to find the leak and it will be an extra 2 days. I’m fine with that. So I expect my car back on Friday. Friday comes and I ask for an update at 11am, get a response minutes before 5pm that my car is ready for collection but they close soon, I can pick it up on Saturday. So I wait until the morning, and wake up to a message saying that 2 items of work were not yet done. So now I must wait until Monday. On Monday I get a message saying my car is ready for collection, I get to the garage, and my car isn’t even there, it’s at another site, now I must wait for them to fetch my car. This level of customer service is just terrible. I am happy for the communications instead of being left in the dark, but they really need to get better and managing client expectations, this went from 2 days, to 4 days, to an entire week. I’m also pretty sure I gave them my car with half a tank of petrol, and now the petrol light is on, but I can’t prove that and could be mistaken.
