Phone not working - how do i find a contact number?

[OK]

Hi - My iphone only makes or recieves call via my internet connection.  I think this may be as result of having temporarily lost my phone.  When i reported it lost, O2 locked the device and then when I found it an hour later, they could only unlock it for use via Web?  I can't find a number or person on O2 webiste to contact to fix this.  Any ideas?

Many thanks,

OK

You need to get customer service to remove all the bars on the account.
