Jolly jingle

I bought a full version. All I got is 5 Christmas songs, not 21 as stated by the developer. Im dissapointed! I tried to report a problem with this but somehow I cant get access to the right place. I sent email to developer and still nothing.
Interesting is on the day I bought this app it said there are total of 21 tracks . Well, today it says the app has only 5 songs. If I knew that earlier I would have never bought it. There are apps which offer 5 or more songs for free.
