Complete inability to keep to a promised completion date.

Sparkling Auto Silver Lakes. Checked 3 times if my vehicle.was going to be ready. Had an apologetic call from Lorna saying the vehicle will be ready at 1300, not 1000. Absolutely 100% guaranteed that the vehicle will be ready. Arrived at 1300. No vehicle..Walked up the area where they are still working on the vehicle.. "maybe 1500". So all plans and appointments have to be shifted. Wont see my business again.
