Charges for SIM not being used

[Tabletcharges]

I received a tablet FOC when I upgraded my phone. I advised at the time that it would only be used for games etc within the home environment. I was given a sim card which has never been inserted into the tablet and hasn't been activated.

I am being charged £4.65 per month for 1GB data/100 free messages which I obviously don't use either.

I can't find an O2 telephone number to discuss this matter and the virtual assistant is very limited for questions to be asked.
