We were trying to get a Visa for Zambia for my Nigerian stepmother. First VisaHQ kept on asking for documents which are not needed by the Zambian Embassy like a notarially certified copy of the passport. Then they said that the Single Entry Visa is only valid for 30 days (which is not true cause it is 90 days) and that we need to apply for a multiple entry visa, which is of course more expensive. And now they are saying that the embassy just informed them that the visa fee is no longer 50$ but now 130$!!! They are really cheating you and try to get the most money out of your pockets. And still we have no visa after more than a month! So hand off!
