How do I report someone under these circumstances?

I am relatively new to using rover. I found a pet sitter who said she would be okay to be paid through Venmo which I thought would be okay, not realizing that this was a violation of the terms of services. We met up and discussed this in person. She texted me thanking me for the "venmo offer" which I initially thought was strange because her boyfriend was the one that initially brought it up.

I initially thought that she was great and she asked me to write a testimony which I did but the other day when I went to go pick up my dog I was mortified!

My girl has a broken leg so she needs special care. She can't be on furniture and needs monitoring constantly because of her injury. When I went to go get her, this sitter's front door was unlocked and wide open. I rang the door bell and called her but no one answered. So I went inside panicking trying to find my dog. Turns out she was upstairs in this sitter's room on a bed that was at least three feet off the ground and the sitter was knocked out cold. I even tried waking this sitter up but she wasn't waking up. I took my dog outside and the sitter only woke up as I was leaving. She seemed very groggy and was defensive when I said that I was terminating services with her. She didn't seems to make any sense and I questioned to myself if she was under the influence of something.

I made a terrible mistake trusting her and being naive to the terms.

Is there a way for me to still report her? What can I do?
