Start charged me without received sim card

[Barryl]

I did not received O2 sim card, why O2 sent me a bill to start charging me.

All networks charge month in advance for contract phones, @Barryl - as well as a cost of living increase of 3 to 8% every April.

I never received sim card from O2, how can they charging me, I didn't obtain any service from O2, it is ridiculous

If you mean you have no contract with O2, and this bill landed out of the blue, then you really need to contact the O2 Fraud Team. They will be able to set you straight, including making sure your bank details or a charge or credit card have not been compromised.

The phone number is 0344 809 0202 from a non-o2 phone.

You are best calling at 8am when the Call Centres open.

For Info - All numbers can be found in the link at the bottom of every page on the o2 site https://o2.co.uk/contactus
