Removing or Replacing TPL_CONTACT_EMAIL_FORM and TPL_CONTACT_DETAILS

Normally I would remove these codes with ease but in this OT Enter Design template I can not Remove or Replace TPL_CONTACT_EMAIL_FORM and TPL_CONTACT_DETAILS on the contact page. And how do I also remove or replace "Sub Page Name" see the attached image and also see the link thinkommcommunications.com/activ/index.php/contacts

In order to change this labels, you need to reach this file /public_html/templates/[your template]/html/com_contact/contact/default_plain.php

I tried to find this solution but i couldn't. Finally i checked all template files and i found it. I hope it works for your site.

Thanks it worked. Even though there were online 88lines I managed to locate the strings and amend them. I am very grateful.
