FireKirin complaint: Won’t send me my money

I sent 10 dollars to them and I won $310 I requested for them to cash app me $280 with my cash app tag… They only sent $50 so when I asked where is the rest they said that refunded it back to a card that I used two weeks prior that was a person that owed me ,in which the card was deleted from my cash app account immediately after the transaction that had nothing to do with sending them that I won off of and they did not ask me can a refund the money because if they did I would have told them no so basically long story short is they refuse to send me the money even though they sent it to the wrong person because of whatever reason and I don’t understand it and I feel it is wrong and this is almost a month ago and I constantly sent text message to them and everything and all I ask for is my money that I won fair and square I don’t feel that it’s right and they are taking me through some emotional anguish behind something that they did which was wrong I need help because I want my money
