Chase has some of the most undisciplined, Attorney General-worthy phone reps you will ever meet in the credit card business. I have been slammed by these clowns into "credit protection plan" rackets I explicitly said I did not want, etc. They will say anything on the phone -- ANYTHING.

If they attempts to withdraw previously awarded miles from your Continental account it would be lawsuit city... you paid for and earned those miles already, fair and square.

If someone tells you Chase intends to try it, get their name, make notes of your conversation and call your state's Attorney General. They are committing wire fraud.
