Helpline number

[Anonymous]

Hey, I need to call o2 and talk to someone about blocking a suspicious number, so anyone know the helpline number? I googled it but multiple numbers come up

202 if on contract or 4445 if on payg

But you can block numbers on your handset, yourself.

Hey thanks for the quick reply, how do I block the number? it says it's unknown number and it doesn't ring, the guy is just getting through to my voice mail.

Ah, sorry, then no you can't do it.
They must be sending a voice message direct to you.
Best to call CS to see if they can help you.

Ah right, thanks very much mate!

No worries mate - If it's abusive or threatening it might also be worth you reporting it to the police.
