When it comes to childcare centers (and home daycare I suppose) I think you need to look at the bigger picture before reacting. Yes, the quality seems to have dropped which is unfortunate and not what you signed up for BUT where does it compare to other centers. Would you be leaving this center for a center that is lower in quality?

I would put some serious thought into what it is that has slipped. Is this something that went from being superior to just average? If so is there superior offered elsewhere or are you leaving an average place for another average place. The next place may have other issues to deal with, issues that may or may not be more bothersome to you.

Obviously you need to factor in that the owner seems to have felt the need to lie. Is there a way to discuss this and figure out why and how to make sure it doesn't happen again.

Lots to figure out. But my first thought would be to ensure that you would be happy with the care at the next place you end up before you severe your relationship here and uproot your daughter.

On that note...what are the impacts of the changes you have noticed on your daughter. Has the loss of quality been something that impacts her, or is it something that an adult notices but ultimately doesn't impact her day? As much as you are the parent and have ultimate say in the matter...it is your child that is there all day, every day and her needs and desire should at least be considered before she is uprooted.
