Implementing the Holder Theme while working on my website

I tried to submit this question 2 days ago, but it did not go through. I purchased the Holder Theme so I could have it as my Landing Page while I continued working on my website. Now the Holder theme has blended with my existing home page and it is a mess. I'm now unable to see the pages I have created, or work with my existing theme.
If this doesn't get fixed, I would like my money back. Thanks.
