Sorry to hear you're having trouble.
However, as this is an open forum I'm afraid that no one here would be able to help. If your suspension has been lifted and you're still unable to redeem points then please contact the Rewards Support Team so they can check to make sure things are fixed. https://rewards.bing.com/support
In the meantime you could try logging out of all Xbox apps and the Store app then restart your device. Make sure that you're using the same account to log in to the PC and all apps when you restart.
