ahhh...I hate the phone companies!!!

I uploaded 20 € at my phone about two weeks ago and today in Lunch break i couldn't write text messages anymore. so I went to the shop complaining and they told me that I had only 20ct left. They didn't tell me that I have to write a free message to a number every time when I top up. So I thought that I had free text and managed it somehow to spend 20€ (!!!) in about two weeks.. maybe three but this wouldn't make it any better!! grrr....
