Hi nleont-gmail-com
Contact us page is showing contact named Get-in-touch and it is managed by this file /templates/ja_rent/html/com_contact/contact/default_address_top.php
You can use language override to change default STRINGS Values or edit this file /language/en-GB/en-GB.tpl_ja_rent.ini to change for example HAVE A QUESTIONS ? text
TPL_CONTACT_ASK="have a questions?"
Hope it helps
