I need my money back

Yea Ive bin playing this game since last year n I got really better this year but I was bidding on (99)Chris Johnson and i spent about 769k bidding on him then my money just disappeared and people were still bidding on him which obviously means the game took my coins n didnt give me the card do can I Juss get the coins back and Ill find a another one to bid on, didnt kno where else to complain. The game is terrific by the way beside that happening to me. My Madden name is ShailleErskine
