I tried contacting the government of Aruba re Entry Requirements at the contact info provided on this website (firstname.lastname@example.org...) 4 times in the last 3 months and have never heard back. I have tried to telephone and haven't been able to reach anyone that way either. I eventually gave up and contacted a lawyer here at home. It has been my experience when trying to contact people and places in Aruba, that answers are a long time in coming or do not come at all.
Therefore, you are not alone. I think it's par for the course and Aruba must be very busy with tourists so perhaps unable to answer everyone.
