Worthless. Did nothing except earn owner 99 cents

This app didnt do anything though I instructed it to delete all contacts; then as a test instructed it to delete most (by selecting ALL then unselecting some... It instead, when I clicked Delete button, asked if I would like to delete 9636, the total number of contacts. It didnt register that I had unselected many of the contacts to retain a contact.) Id like a working app (it would be nice if someone told me of a working automated way to remove hundreds of duplicates) or my money returned.
