I can't imagine any groomer NOT CALLING before they closed up for the night. What they did is ridiculous!!! I would definitely call the Better Business Bureau or the local Chamber of Commerce and discuss the situation with them. I, personally, would not let this rest until I received some better form of apology from these people.
Technically, they did hold your pet ransoom....and for her to charge you for the work done after all the stress that you've been through...it's just horrible. Obviously she doesn't care for animals at all....being as she put your cat in a crate and was ok with leaving her there for the night.
I'm so sorry you (and your poor cat!) had to go through this situation...this lady should NOT be in business!
