Just remembered that we've had the same problem not getting through to the MoH in May. Sorry that I forgot about this. In May I called the Ministry and they told me to get in contact with
Mrs. R. Veerapen, Senior Chief Executive
Her email address is firstname.lastname@example.org
(this one should be working - at least it did in May)
phone +230 201 1912, fax +230 2080376
Hope it will be okay now and again sorry!
