ACT score cancelled? Can I send them another score now?

Does anybody know what happens when your ACT score is cancelled after admission decision??
I got a mail about my ACT score(33 in September) about cheating cuz my score has increased so much as I said in my other post.
I would like to know what I can do if they decide to cancel my score.
Can I send my other score which is 28 in April after they cancel?? Will colleges still accept it??Will they cancel my admission when my score drops down to 28?
Or can I send the 28 act now?? and change my scores in my collegeboard score part to my 28 ACT scores??
Will they say that I lied in my application when my 33 is cancelled and I resend the 28?
THANKS!

HI, My child has recently been placed in this same situation. I was wondering what you have found out about this? Will colleges rescind their acceptance offer. This is a nightmare and we can’t believe this is happening to us. My child has already been accepted and we just received the letter from ACT. He took the test in June. What ended up of your situation?
