One week before one from my letters next day  returned to me.

I went to post office and and asked why they returned my letter, they laughed and took it back to delivery it.

Australian Post Office is very expensive comparing with other countries and its services is not good!

Lost letters, expensive deliveries, huge delays on Christmas etc.

Why they do not employ many casual workers to do their job?

Post Office as ebay too want the minimum cost and  the maximum profit!
