Limit to unlimited texts?

[Anonymous]

I became a new member to O2 last month and ay £7.50 for unlimited texts, which expires at the end of this month. I got a text from O2 saying that I have ran out of texts...there's a limit on unlimited texts? I had £2.50 left, now just £1.78 so I'm already being charged for it. 

Anyone care to exlplain what is going on?

Whatsapp has been of enormous benefit to me with my son living in Berlin, must have saved hundreds of pounds on international text rates.
