Review threatened by the Post Office because I speak the truth, they are thieves stealing money

I went to the main Postoffice in Accra to collect my package of foodstuff. He charged me half of the worth of the package while foodstuff is supposed to be dutyfree as written in their customs procedures. Then he told me only diplomatic people get their stuff free which is also a lie. He keeps changing his stories. The postoffice worker (John Kwotuah) even treatened me on facebook he will get me arrested next time so that I know my limit. There will be no next time, but the only people that should get arrested is those thieves at the postoffice for taking people's money while they are not supposed to do that. Sending a package by post to Ghana is not the same as anywhere else in the world, in Ghana they charge you any amount they like, so the people can never collect their stuff free of charge which is ridiculous.
