difficulty getting a PO Box

I have been trying for months now to get a po box but every time i walk into a branch or call a branch or head office, i am always told that there are none available. i was told to call back 1 march as the renewal fees were due 28feb and apparently every single person who owns a po box in doha has renewed (which i find a little hard to believe). I get the feeling that they are just being lazy and don't want to do the paperwork. All i want is a po box because i'm having to send my mail to a friend in the uk at the moment and collect it from her when i visit. does anyone have any suggestions???? thanks :-)
