Did you sign a contract saying horses would be worked x amount of days for x amount of money? If so, bring it in and demand your money back, and find a new trainer.
That is completely disrespectful and outrageous that a trainer, that is paid to work your horse, doesn't do her job. My thinking is, You paid and got no results, you get your money back.
My trainer wasn't able to work one of my horses for 5 days due to a family member passing away. She told me to keep the horse there an extra week so she can make up the time that was missed out on.
