Owner cannot be contacted. How do I contact them via msg their profile and not their cell?

Recieved a text about a new booking request with client and the Rover number connected me to a stranger who was not the client or needed my services and was very mad I kept asking questions trying to figure out what the mix up was.

Thinking the client is new and signed up with the wrong cell number. Tried using the website and that still didnt work. They wanted to book starting tomorrow and I have no idea what time they need their dog walked or when I can schedule a meet and greet. I scheduled one with the message to contact me and look at their info. Hopefully she will see it and correct it. I sent a ticket to the site and they said to wait up to two days but I don't want to wait that long or lose my booking

I am unsure on what else to do at this point but it's frustrating.
