Anyone knows how to withdraw listing from Tellus?

First time listing my property through Tellus App. Not sure if I like it. The leads came in didn’t collect the potential applicants’ email address while I don’t want to call people through my cell phone number at this stage, I prefer email. 

Seems like I couldn’t find a tel number to talk to someone when I need a quick response.

Anyone knows how to bring my listing down from Tellus?

Thank you!
