Had to reset

After playing for many months, when I tried to add new games, I got a message I had reached my limit of games when I actually only had a couple. Finally had to delete the app and start over - lost games I was playing and all stats! Now on the app I downloaded I started new games and after a few turns the opposing players never played and I am unable to nudge or force forfeit- these games are over a month old. How can I delete them?
