I got robbed

So I really do love this game! Its a great way to past the time but I have one really big problem with this app and the company who made it. I downloaded this game a couple years ago and I bought the extra maps. I recently redownloaded the game and to my surprise its asking me to buy the extra maps again. I lost the extra maps that I had previously bought. If anyone could help me with this problem I would really appreciate it!!
