Not possible. Provide your account number please.

What is possible is to reassign an alias. say I bought the alias "google", but I assigned a wrong URI to it. Then I would assign the alias again (with 1NXT fee) and change the URI. Only the owner of an alias can reassign it.

Another possibility that could have happened to you is that you set the deadline too short. Say you set the deadline to 1 minute, and the next block gets created after 2 minutes, then your alias assignement gets cancelled because it was not included in a block before hitting deadline.
