Why have I been charged for texts when I have unlimited texts?

[Anonymous]

I have been charged for texts when I haven't sent many - i'm supposed ot have unlimited texts. How do I find out how to get a refund or if my contract has changed without my knowledge.

Check your tariff in My O2 for any changes. 

Also have a read about mms messages being converted from simple texts.

Check you aren't sending MMS messages by mistake https://community.o2.co.uk/t5/Other-Products-and-Services/Accidental-MMS-Sending-and-How-to-Avoid-it...
Your MyO2 will tell you why you have been charged http://www.o2.co.uk/myo2
If you think you should be refunded you need to call customer service http://www.o2.co.uk/contactus
