I can't sell players. 99 coins

I haven't been able to sell my players for over a month WHICH ARE FALLING IN PRICE, and as I understand it, no one will compensate for this. All players have a price tag of 90 coins when sold, which does not change. Nothing helps, not re-logins, not reinstallations. Solve the problem EA! Players are already turning a blind eye to a huge pile of glitches, are you able to fix at least the critical ones?
