Unfortunately, Sittercity cannot get involved with monetary disputes as we are not an agency, and all transactions occur off of our site. We would recommend reaching out to your employer about your payment in hopes that you will be able to come to a mutual agreement.
In the meantime, you can reach out to your local government office to see what laws are in place about monetary dispute issues.
Please be sure to check out our Trust & Safety Center for additional important information regarding trust & safety on Sittercity.
