Need service

I bought 2186 Crossword(Benjamin Lochmann) 1500 coins as in app for remove ads on Fed,07 2015. Its $1.99. Last day, this app is not working well so delete and download again, but I found ads appear. Do I need buy coins every time after download again? You said it will be removed permanently. One more thing, your contact info is hardly find out. At last, I sent email to lochmann, but no answer yet. Not good customer services.. I cannot find a half star..
