Beggars can't be choosers

I get this statement from a local Internet service provider. This statement tells me that I owe money. Funny how last month I had to tell this company that I've paid my internet up till March/05. It seems these incompetents just don't get it. Why am I asked to pay for something when I have already paid? Sounds kinda stupid doesn't it? Then I get told that they'll look into it. Great, so I can expect a reply like I got last month "sorry for the error, the necessary corrections have been made". So I guess I should be expecting an invoice next month:( And I'm sure I'll see an outstanding balance from the previous month and interest added to that. Kinda makes me wonder how these businesses have managed to stay afloat (profiting by these "errors" I suppose). I wish there was another internet service provider in my neck of the woods. But guess what, beggars can't be choosers.
