Change link within block http://www.ascoworld.com/services

On the above page, there is a block with three icons that links to the wrong pages. I want to change where they link to but can't seem to find out how. Apologies, but I am as new as can be at this. I didn't create the website and have never used Drupal before, I just got passed it and told to fix these issues.

Thanks!
The page layout is broken but I assume that you are talking about Services menu block. Based on the HTML source it is a menu block and a main menu to be specific. So to the change the link go to Structure &gt; Menus &gt; Main Menu and change the link path there.

UPDATE:

Since the page is broken in my end my above answer is wrong. As @iamroald comment it is created via Views. Go to Structure &gt; Views &gt; Services. It seems like there is a Token substitution in there.
