Text not related to my site showing up, descriptions in google….HELP!

Hello,
I am new to the forums, hope I’m in the right place. I hired a offshore company to build my website for my cell phone repair service but they are terrible at providing support. I am having a problem with my site when viewed on certain computers and mobile phones. For some reason there is the word “Cancer” displaying right above my logo on my site when viewed on certain computers and all mobile phones. It has to be sample text that was added when the template was made but how to I remove it? Also, how do I edit descriptions for google when a specific page is searched in google? Such as if someone searched “mobile miracles terms of service” it has a description of a page about cancer as opposed to when I search “mobile miracles” in google the home page has the correct description. I need to know how to make the description the same for every other page. Below you will find the example from my iPhone 4s.
