Money stolen in app

I made a purchase for a 39.99 reward and didnt receive anything. I emailed them 3 times and all I received was an email stating that they were going to keep my ticket open. Its been a week and still havent heard anything nor have I received a refund or at least my reward. Truly a headache and I hate wasting money.
