Paying for apps with different titles but same content

First, let me say, that I loved this app. I still would love this app if it was working properly. I cannot add any more inductions or topics so I am limited as to what I can do in the mix. The only reason I purchased this relaxation app over others is that it offered the ability to mix and match programs and suddenly I can no longer do that.
I made an effort to contact the maker but no response. This is disappointing.
I would give it five stars but if the app isnt working and wont be fixed to do what it was originally supposed to do then I am left with a disappointing purchase.

New information about this app:
I have been enjoying Relax plus. There was a glitch where I couldnt download add ons but that appears to be fixed.

I was happy to see that I could download add ons again and I went ahead and downloaded Confidence only to find out it is exactly the same as one of the other add ons, its either Believe in Yourself or Social phobia but it is exactly the same and now I have paid twice for the same thing with different titles.

I am really taken aback by this and would like a refund. Now I am not sure that I can trust that I am receiving a quality product. What assurance can you provide that many of the add ons are unique and not mere copies of other ones with only the titles being different like what I have experienced here?
