Can’t Remove Contact Section From MyListing Site

You should be able to edit that sidebar template to remove the contact group everywhere. As SirLouen noted, this is theme specific so messaguing the MyListing support is a good option if you aren’t sure where or how to edit the sidebar template.

Alternatively you can use custom CSS, but note this will hide EVERY element that has the class ‘blocc-type-contact_form’ on your website, so it may have unintended consequences. Custom CSS:
.blocc-type-contact_form {
display: none;
}
