Leaving Deloitte during training contract


I know there are a few similar topics on the site but I need specific information if anybody’s been in the same situation.

I’ll be leaving Deloitte about 3/4 of the way through my ACA training contract. I’ve done all of the exams. Does anybody know how much they’ll ask me to pay back?

If anyone has been in my position I’d be very grateful for advice. Thanks.
