How can I contact a seller

click on there profile and then there is a send private message button in the top right of there page. they will not just see that they have a message on here it will send them a email.

That didn't help I don't see anything to send a private message I'm on the app on my phone whenever I message it just says to fix phone number

ahhh you might need to try this on a computer . I dont know how this workd on the phone but it sounds like it isnt compatible.

I am trying to do that on my computer but I don't see anything on the top right that I can click on to contact the dealer.

I have sent messages to a private seller. Cargurus responded after I contacted them because I did not get a response from seller. Cargurus says that it's because I haven't linked my bank account. Lol. I don't think the seller even gets the messages.
