My weekly rewards on rivals & my players that got a red card on ul team

hey , ive had this problem for a year now and i genuinely think that my ultimate team is broken because when a player of mine gets a red card i cant get him back ever again even if i send him to my club and do a couple of matches without him. there are like 20 players on my team that are banned and unusable cuz they wont get unbanned. Secondly , i got packs from my weekly rewards A toty and smth else but they never appear on my packs this happened to me a lot and i tried everything, i need help.
