Unfair play in Canasta

I have complained about this issue in canasta for months. I have been playing since 2002 and since EA took over I cannot get past beginner stage. I pay my dues every year I buy gems. You fix the issue for a day or so then the game goes back to players stalling if they are losing, or leave a bot takes over and wins. They only seems to be certain players who get ahead. Come on fix the problem.
